speedup dead root detection during orphan cleanup, eg. when there\n are many deleted subvolumes waiting to be cleaned, the trees are\n now looked up in radix tree instead of a O(N^2) search\n\n - snapshot creation with inherited qgroup will mark the qgroup\n inconsistent, requires a rescan\n\n -

factor out backreference iteration, to be used by ordinary\n backreferences and relocation code\n\n - improved global block reserve utilization\n * better logic to serialize requests\n * increased maximum available for unlink\n * improved handling on large pages (64K)\n\n - direct io cleanups and fixes\n * simplify layering, where cloned bios were unnecessarily created\n for some cases\n * error handling fixes (submit, endio)\n * remove repair worker thread, used to avoid deadlocks during\n repair\n\n - refactored block group reading code, preparatory work for new type\n of block group storage that should improve mount time on large\n filesystems\n\n Cleanups:\n\n - cleaned up (and slightly sped up) set/get helpers for metadata data\n structure members\n\n - root bit REF_COWS got renamed to SHAREABLE to reflect the that the\n blocks of the tree get shared either among subvolumes or with the\n relocation trees\n\n Fixes:\n\n - when subvolume deletion fails due to ENOSPC, the filesystem is not\n turned read-only\n\n - device scan deals with devices from other filesystems that changed\n ownership due to overwrite (mkfs)\n\n - fix a race between scrub and block group removal/allocation\n\n - fix long standing bug of a runaway balance operation, printing the\n same line to the syslog, caused by a stale status bit on a reloc\n tree that prevented progress\n\n -

The mechanism used for penalizing is similar to\nmemory.high penalty (sleep on return to user space).\n\nThat is not to say that the knob itself is equivalent to memory.high.\nThe objective is more to protect the system from potentially buggy tasks\nconsuming a lot of swap and impacting other tasks, or even bringing the\nwhole system to stand still with complete SWAP exhaustion. Hopefully\nwithout the need to find per-task hard limits.\n\nSlowing misbehaving tasks down gradually allows user space oom killers\nor other protection mechanisms to react. oomd and earlyoom already do\nkilling based on swap exhaustion, and memory.swap.high protection will\nhelp implement such userspace oom policies more reliably.\n\nWe can use one counter for number of pages allocated under pressure to\nsave struct task space and avoid two separate hierarchy walks on the hot\npath. The exact overage is calculated on return to user space, anyway.\n\nTake the new high limit into account when determining if swap is \"full\".\nBorrowing the explanation from Johannes:\n\n The idea behind \"swap full\" is that as long as the workload has plenty\n of swap space available and it\u0027s not changing its memory contents, it\n makes sense to generously hold on to copies of data in the swap device,\n even after the swapin. A later reclaim cycle can drop the page without\n any IO. Trading disk space for IO.\n\n But the only two ways to reclaim a swap slot is when they\u0027re faulted\n in and the references go away, or by scanning the virtual address space\n like swapoff does - which is very expensive (one could argue it\u0027s too\n expensive even for swapoff, it\u0027s often more practical to just reboot).\n\n So at some point in the fill level, we have to start freeing up swap\n slots on fault/swapin. Otherwise we could eventually run out of swap\n slots while they\u0027re filled with copies of data that is also in RAM.\n\n We don\u0027t want to OOM a workload because its available swap space is\n filled with redundant cache.\n\nSigned-off-by: Jakub Kicinski \u003ckuba@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nAcked-by: Johannes Weiner \u003channes@cmpxchg.org\u003e\nCc: Tejun Heo \u003ctj@kernel.org\u003e\nCc: Chris Down \u003cchris@chrisdown.name\u003e\nCc: Shakeel Butt \u003cshakeelb@google.com\u003e\nCc: Michal Hocko \u003cmhocko@kernel.org\u003e\nCc: Hugh Dickins \u003chughd@google.com\u003e\nLink: http://lkml.kernel.org/r/20200527195846.102707-5-kuba@kernel.org\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d1663a907bd348f912b7f7088e83ca1b6fd3309f", "tree": "b5bb5b03cd6958cead5ce23c45680dff016062b8", "parents": [ "ff144e69f7331eff070f31edf22bc9123d6d6d27" ], "author": { "name": "Jakub Kicinski", "email": "kuba@kernel.org", "time": "Mon Jun 01 21:49:49 2020 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jun 02 10:59:09 2020 -0700" }, "message": "mm/memcg: move cgroup high memory limit setting into struct page_counter\n\nHigh memory limit is currently recorded directly in struct mem_cgroup.\nWe are about to add a high limit for swap, move the field to struct\npage_counter and add some helpers.\n\nSigned-off-by: Jakub Kicinski \u003ckuba@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nReviewed-by: Shakeel Butt \u003cshakeelb@google.com\u003e\nAcked-by: Johannes Weiner \u003channes@cmpxchg.org\u003e\nCc: Chris Down \u003cchris@chrisdown.name\u003e\nCc: Hugh Dickins \u003chughd@google.com\u003e\nCc: Michal Hocko \u003cmhocko@kernel.org\u003e\nCc: Tejun Heo \u003ctj@kernel.org\u003e\nLink: http://lkml.kernel.org/r/20200527195846.102707-4-kuba@kernel.org\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "ff144e69f7331eff070f31edf22bc9123d6d6d27", "tree": "991e6abd950f1e87628aac197b9b16060840208f", "parents": [ "8a5dbc657e1233c907f84f2c6192d3a3cf0026b3" ], "author": { "name": "Jakub Kicinski", "email": "kuba@kernel.org", "time": "Mon Jun 01 21:49:45 2020 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jun 02 10:59:09 2020 -0700" }, "message": "mm/memcg: move penalty delay clamping out of calculate_high_delay()\n\nWe will want to call calculate_high_delay() twice - once for memory and\nonce for swap, and we should apply the clamp value to sum of the\npenalties.

However at the moment these stats are\nnot updated consistently at the system level and the ratio of these are\nnot very meaningful. The pgsteal and pgscan are updated for only global\nreclaim while pgrefill gets updated for global as well as cgroup\nreclaim.\n\nPlease note that this difference is only for system level vmstats. The\ncgroup stats returned by memory.stat are actually consistent. The\ncgroup\u0027s pgsteal contains number of reclaimed pages for global as well\nas cgroup reclaim. So, one way to get the system level stats is to get\nthese stats from root\u0027s memory.stat, so, expose memory.stat for the root\ncgroup.\n\nFrom Johannes Weiner:\n\tThere are subtle differences between /proc/vmstat and\n\tmemory.stat, and cgroup-aware code that wants to watch the full\n\thierarchy currently has to know about these intricacies and\n\ttranslate semantics back and forth.\n\n\tGenerally having the fully recursive memory.stat at the root\n\tlevel could help a broader range of usecases.\n\nWhy not fix the stats by including both the global and cgroup reclaim\nactivity instead of exposing root cgroup\u0027s memory.stat? The reason is\nthe benefit of having metrics exposing the activity that happens purely\ndue to machine capacity rather than localized activity that happens due\nto the limits throughout the cgroup tree. Additionally there are\nuserspace tools like sysstat(sar) which reads these stats to inform\nabout the system level reclaim activity.

After the swap device becomes fragmented so\nthat there\u0027s no free swap cluster, the swap device will be scanned\nlinearly to find the free swap slots. swap_info_struct-\u003ecluster_next is\nthe next scanning base that is shared by all CPUs. So nearby free swap\nslots will be allocated for different CPUs. The probability for\nmultiple CPUs to operate on the same 64 MB trunk is high. This causes\nthe lock contention on the swap cache.\n\nTo solve the issue, in this patch, for SSD swap device, a percpu version\nnext scanning base (cluster_next_cpu) is added. Every CPU will use its\nown per-cpu next scanning base. And after finishing scanning a 64MB\ntrunk, the per-cpu scanning base will be changed to the beginning of\nanother randomly selected 64MB trunk. In this way, the probability for\nmultiple CPUs to operate on the same 64 MB trunk is reduced greatly.\nThus the lock contention is reduced too. For HDD, because sequential\naccess is more important for IO performance, the original shared next\nscanning base is used.\n\nTo test the patch, we have run 16-process pmbench memory benchmark on a\n2-socket server machine with 48 cores. One ram disk is configured as the\nswap device per socket. The pmbench working-set size is much larger than\nthe available memory so that swapping is triggered. The memory read/write\nratio is 80/20 and the accessing pattern is random. In the original\nimplementation, the lock contention on the swap cache is heavy. The perf\nprofiling data of the lock contention code path is as following,\n\n _raw_spin_lock_irq.add_to_swap_cache.add_to_swap.shrink_page_list: 7.91\n _raw_spin_lock_irqsave.__remove_mapping.shrink_page_list: 7.11\n _raw_spin_lock.swapcache_free_entries.free_swap_slot.__swap_entry_free: 2.51\n _raw_spin_lock_irqsave.swap_cgroup_record.mem_cgroup_uncharge_swap: 1.66\n _raw_spin_lock_irq.shrink_inactive_list.shrink_lruvec.shrink_node: 1.29\n _raw_spin_lock.free_pcppages_bulk.drain_pages_zone.drain_pages: 1.03\n _raw_spin_lock_irq.shrink_active_list.shrink_lruvec.shrink_node: 0.93\n\nAfter applying this patch, it becomes,\n\n _raw_spin_lock.swapcache_free_entries.free_swap_slot.__swap_entry_free: 3.58\n _raw_spin_lock_irq.shrink_inactive_list.shrink_lruvec.shrink_node: 2.3\n _raw_spin_lock_irqsave.swap_cgroup_record.mem_cgroup_uncharge_swap: 2.26\n _raw_spin_lock_irq.shrink_active_list.shrink_lruvec.shrink_node: 1.8\n _raw_spin_lock.free_pcppages_bulk.drain_pages_zone.drain_pages: 1.19\n\nThe lock contention on the swap cache is almost eliminated.\n\nAnd the pmbench score increases 18.5%. The swapin throughput increases\n18.7% from 2.96 GB/s to 3.51 GB/s. While the swapout throughput increases\n18.5% from 2.99 GB/s to 3.54 GB/s.\n\nWe need really fast disk to show the benefit.

To solve the problem, in this patch, we will try to scan a\nlittle more swap slots with restricted effort to batch the swap slots\nallocation even if the swap device is fragmented. Test shows that the\nbenchmark score can increase up to 37.1% with the patch. Details are as\nfollows.\n\nThe swap code has a per-cpu cache of swap slots. These batch swap space\nallocations to improve swap subsystem scaling. In the following code\npath,\n\n add_to_swap()\n get_swap_page()\n refill_swap_slots_cache()\n get_swap_pages()\n\t scan_swap_map_slots()\n\nscan_swap_map_slots() and get_swap_pages() can return multiple swap\nslots for each call. These slots will be cached in the per-CPU swap\nslots cache, so that several following swap slot requests will be\nfulfilled there to avoid the lock contention in the lower level swap\nspace allocation/freeing code path.\n\nBut this only works when there are free swap clusters. If a swap device\nbecomes so fragmented that there\u0027s no free swap clusters,\nscan_swap_map_slots() and get_swap_pages() will return only one swap\nslot for each call in the above code path. Effectively, this falls back\nto the situation before the swap slots cache was introduced, the heavy\nlock contention on the swap related locks kills the scalability.\n\nWhy does it work in this way? Because the swap device could be large,\nand the free swap slot scanning could be quite time consuming, to avoid\ntaking too much time to scanning free swap slots, the conservative\nmethod was used.\n\nIn fact, this can be improved via scanning a little more free slots with\nstrictly restricted effort. Which is implemented in this patch. In\nscan_swap_map_slots(), after the first free swap slot is gotten, we will\ntry to scan a little more, but only if we haven\u0027t scanned too many slots\n(\u003c LATENCY_LIMIT). That is, the added scanning latency is strictly\nrestricted.\n\nTo test the patch, we have run 16-process pmbench memory benchmark on a\n2-socket server machine with 48 cores. Multiple ram disks are\nconfigured as the swap devices. The pmbench working-set size is much\nlarger than the available memory so that swapping is triggered. The\nmemory read/write ratio is 80/20 and the accessing pattern is random, so\nthe swap space becomes highly fragmented during the test. In the\noriginal implementation, the lock contention on swap related locks is\nvery heavy. The perf profiling data of the lock contention code path is\nas following,\n\n _raw_spin_lock.get_swap_pages.get_swap_page.add_to_swap: 21.03\n _raw_spin_lock_irq.shrink_inactive_list.shrink_lruvec.shrink_node: 1.92\n _raw_spin_lock_irq.shrink_active_list.shrink_lruvec.shrink_node: 1.72\n _raw_spin_lock.free_pcppages_bulk.drain_pages_zone.drain_pages: 0.69\n\nWhile after applying this patch, it becomes,\n\n _raw_spin_lock_irq.shrink_inactive_list.shrink_lruvec.shrink_node: 4.89\n _raw_spin_lock_irq.shrink_active_list.shrink_lruvec.shrink_node: 3.85\n _raw_spin_lock.free_pcppages_bulk.drain_pages_zone.drain_pages: 1.1\n _raw_spin_lock_irqsave.pagevec_lru_move_fn.__lru_cache_add.do_swap_page: 0.88\n\nThat is, the lock contention on the swap locks is eliminated.\n\nAnd the pmbench score increases 37.1%. The swapin throughput increases\n45.7% from 2.02 GB/s to 2.94 GB/s. While the swapout throughput increases\n45.3% from 2.04 GB/s to 2.97 GB/s.\n\nSigned-off-by: \"Huang, Ying\" \u003cying.huang@intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nAcked-by: Tim Chen \u003ctim.c.chen@linux.intel.com\u003e\nCc: Dave Hansen \u003cdave.hansen@intel.com\u003e\nCc: Michal Hocko \u003cmhocko@suse.com\u003e\nCc: Minchan Kim \u003cminchan@kernel.org\u003e\nCc: Hugh Dickins \u003chughd@google.com\u003e\nLink: http://lkml.kernel.org/r/20200427030023.264780-1-ying.huang@intel.com\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "7b9e2de130954af174e6f7aff278cf1ec5f39675", "tree": "2ebb38107c36c0c77738259f6a46fd6a3dd6e517", "parents": [ "fdff1debb9650ea43617487500f48168ce432cb7" ], "author": { "name": "Wei Yang", "email": "richard.weiyang@gmail.com", "time": "Mon Jun 01 21:49:07 2020 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jun 02 10:59:09 2020 -0700" }, "message": "mm/swapfile.c: omit a duplicate code by compare tmp and max first\n\nThere are two duplicate code to handle the case when there is no available\nswap entry.

is\nused most of the time as if we had only misses (this happens both with\ncluster and vma readahead), for example:\n\nr::swapin_nr_pages(unsigned long offset):unsigned long:$retval\n COUNT EVENT\n 36948 $retval \u003d 8\n 44151 $retval \u003d 4\n 49290 $retval \u003d 1\n 527771 $retval \u003d 2\n\nChecking if the swap entry is present in the swap cache, instead, allows\nto properly update the readahead statistics and the heuristic behaves in a\nbetter way during swapoff, selecting a bigger readahead size:\n\nr::swapin_nr_pages(unsigned long offset):unsigned long:$retval\n COUNT EVENT\n 1618 $retval \u003d 1\n 4960 $retval \u003d 2\n 41315 $retval \u003d 4\n 103521 $retval \u003d 8\n\nIn terms of swapoff performance the result is the following:\n\nTesting

The purpose of this is to avoid deadlock that happen when\nthe PF_LESS_THROTTLE process must write for any dirty pages to be freed,\nbut it is being thottled and cannot write.\n\nThis approach was designed when all threads were blocked equally,\nindependently on which device they were writing to, or how fast it was.\nSince that time the writeback algorithm has changed substantially with\ndifferent threads getting different allowances based on non-trivial\nheuristics. This means the simple \"add 25%\" heuristic is no longer\nreliable.\n\nThe important issue is not that the daemon needs a *larger* dirty page\nallowance, but that it needs a *private* dirty page allowance, so that\ndirty pages for the \"client\" bdi that it is helping to clear (the bdi\nfor an NFS filesystem or loop block device etc) do not affect the\nthrottling of the daemon writing to the \"final\" bdi.\n\nThis patch changes the heuristic so that the task is not throttled when\nthe bdi it is writing to has a dirty page count below below (or equal\nto) the free-run threshold for that bdi. This ensures it will always be\nable to have some pages in flight, and so will not deadlock.\n\nIn a steady-state, it is expected that PF_LOCAL_THROTTLE tasks might\nstill be throttled by global threshold, but that is acceptable as it is\nonly the deadlock state that is interesting for this flag.\n\nThis approach of \"only throttle when target bdi is busy\" is consistent\nwith the other use of PF_LESS_THROTTLE in current_may_throttle(), were\nit causes attention to be focussed only on the target bdi.\n\nSo this patch\n - renames PF_LESS_THROTTLE to PF_LOCAL_THROTTLE,\n - removes the 25% bonus that that flag gives, and\n - If PF_LOCAL_THROTTLE is set, don\u0027t delay at all unless the\n global and the local free-run thresholds are exceeded.\n\nNote that previously realtime threads were treated the same as\nPF_LESS_THROTTLE threads. This patch does *not* change the behvaiour\nfor real-time threads, so it is now different from the behaviour of nfsd\nand loop tasks.
