per-file encryption from f2fs\ntree to fs/crypto\") moved the f2fs crypto files to fs/crypto/ and\nrenamed the symbol prefixes from \"f2fs_\" to \"fscrypt_\" (and from \"F2FS_\"\nto just \"FS\" for preprocessor symbols).\n\nBecause of the symbol renaming, it\u0027s a bit hard to see it as a file\nmove: use\n\n git show -M30 0b81d07790726\n\nto lower the rename detection to just 30% similarity and make git show\nthe files as renamed (the header file won\u0027t be shown as a rename even\nthen - since all it contains is symbol definitions, it looks almost\ncompletely different).\n\nEven with the renames showing as renames, the diffs are not all that\neasy to read, since so much is just the renames. But Eric Biggers\nnoticed that it\u0027s not just all renames: the initialization of the\nxts_tweak had been broken too, using the inode number rather than the\npage offset.\n\nThat\u0027s not right - it makes the xfs_tweak the same for all pages of each\ninode. It _might_ make sense to make the xfs_tweak contain both the\noffset _and_ the inode number, but not just the inode number.\n\nReported-by: Eric Biggers \u003cebiggers3@gmail.com\u003e\nCc: Jaegeuk Kim \u003cjaegeuk@kernel.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "4f1b50c3e3082b31c94cee2b897bd9f5d0f3e7c8", "tree": "5dcb8b81088f918e74bc58a2a92e80564be6d227", "parents": [ "afc54992296a5e7f7d2e41456ed90789b01a4e7b" ], "author": { "name": "Allen Hubbe", "email": "Allen.Hubbe@emc.com", "time": "Mon Mar 21 04:53:14 2016 -0400" }, "committer": { "name": "Jon Mason", "email": "jdmason@kudzu.us", "time": "Sat Mar 26 11:44:33 2016 -0400" }, "message": "NTB: Remove _addr functions from ntb_hw_amd\n\nKernel zero day testing warned about address space confusion.

However, we only check\nthe migratetype of the pageblock where buddy merging has been initiated,\nnot the migratetype of the buddy pageblock (or group of pageblocks)\nwhich can be MIGRATE_ISOLATE.\n\nJoonsoo has suggested checking for buddy migratetype as part of\npage_is_buddy(), but that would add extra checks in allocator hotpath\nand bloat-o-meter has shown significant code bloat (the function is\ninline).\n\nThis patch reduces the bloat at some expense of more complicated code.\nThe buddy-merging while-loop in __free_one_page() is initially bounded\nto pageblock_border and without any migratetype checks. The checks are\nplaced outside, bumping the max_order if merging is allowed, and\nreturning to the while-loop with a statement which can\u0027t be possibly\nconsidered harmful.\n\nThis fixes the accounting bug and also removes the arguably weird state\nin the original commit 3c605096d315 where buddies could be left\nunmerged.\n\nFixes: 3c605096d315 (\"mm/page_alloc: restrict max order of merging on isolated pageblock\")\nLink: https://lkml.org/lkml/2016/3/2/280\nSigned-off-by: Vlastimil Babka \u003cvbabka@suse.cz\u003e\nReported-by: Hanjun Guo \u003cguohanjun@huawei.com\u003e\nTested-by: Hanjun Guo \u003cguohanjun@huawei.com\u003e\nAcked-by: Joonsoo Kim \u003ciamjoonsoo.kim@lge.com\u003e\nDebugged-by: Laura Abbott \u003clabbott@redhat.com\u003e\nDebugged-by: Joonsoo Kim \u003ciamjoonsoo.kim@lge.com\u003e\nCc: Mel Gorman \u003cmgorman@techsingularity.net\u003e\nCc: \"Kirill A.

Such a task (oom victim) will get an access to memory reserves\nvia mark_oom_victim to allow a forward progress should there be a need\nfor additional memory during exit path.\n\nIt has been shown (e.g. by Tetsuo Handa) that it is not that hard to\nconstruct workloads which break the core assumption mentioned above and\nthe OOM victim might take unbounded amount of time to exit because it\nmight be blocked in the uninterruptible state waiting for an event (e.g.\nlock) which is blocked by another task looping in the page allocator.\n\nThis patch reduces the probability of such a lockup by introducing a\nspecialized kernel thread (oom_reaper) which tries to reclaim additional\nmemory by preemptively reaping the anonymous or swapped out memory owned\nby the oom victim under an assumption that such a memory won\u0027t be needed\nwhen its owner is killed and kicked from the userspace anyway. There is\none notable exception to this, though, if the OOM victim was in the\nprocess of coredumping the result would be incomplete. This is\nconsidered a reasonable constrain because the overall system health is\nmore important than debugability of a particular application.\n\nA kernel thread has been chosen because we need a reliable way of\ninvocation so workqueue context is not appropriate because all the\nworkers might be busy (e.g. allocating memory). Kswapd which sounds\nlike another good fit is not appropriate as well because it might get\nblocked on locks during reclaim as well.\n\noom_reaper has to take mmap_sem on the target task for reading so the\nsolution is not 100% because the semaphore might be held or blocked for\nwrite but the probability is reduced considerably wrt. basically any\nlock blocking forward progress as described above. In order to prevent\nfrom blocking on the lock without any forward progress we are using only\na trylock and retry 10 times with a short sleep in between. Users of\nmmap_sem which need it for write should be carefully reviewed to use\n_killable waiting as much as possible and reduce allocations requests\ndone with the lock held to absolute minimum to reduce the risk even\nfurther.\n\nThe API between oom killer and oom reaper is quite trivial.\nwake_oom_reaper updates mm_to_reap with cmpxchg to guarantee only\nNULL-\u003emm transition and oom_reaper clear this atomically once it is done\nwith the work. This means that only a single mm_struct can be reaped at\nthe time. As the operation is potentially disruptive we are trying to\nlimit it to the ncessary minimum and the reaper blocks any updates while\nit operates on an mm. mm_struct is pinned by mm_count to allow parallel\nexit_mmap and a race is detected by atomic_inc_not_zero(mm_users).\n\nSigned-off-by: Michal Hocko \u003cmhocko@suse.com\u003e\nSuggested-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nSuggested-by: Mel Gorman \u003cmgorman@suse.de\u003e\nAcked-by: Mel Gorman \u003cmgorman@suse.de\u003e\nAcked-by: David Rientjes \u003crientjes@google.com\u003e\nCc: Mel Gorman \u003cmgorman@suse.de\u003e\nCc: Tetsuo Handa \u003cpenguin-kernel@I-love.SAKURA.ne.jp\u003e\nCc: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Hugh Dickins \u003chughd@google.com\u003e\nCc: Andrea Argangeli \u003candrea@kernel.org\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "69b27baf00fa9b7b14b3263c105390d1683425b2", "tree": "6590848e3ff8d0ee4e0624a3f93082c6953906e7", "parents": [ "1701f680407c6cc05121566cef5293d33881fe71" ], "author": { "name": "Andrew Morton", "email": "akpm@linux-foundation.org", "time": "Fri Mar 25 14:20:21 2016 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Mar 25 16:37:42 2016 -0700" }, "message": "sched: add schedule_timeout_idle()\n\nThis will be needed in the patch \"mm, oom: introduce oom reaper\".\n\nAcked-by: Michal Hocko \u003cmhocko@suse.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "2d5ae5c2c7025b3bac264545f88b4d958fbdccc8", "tree": "b61714e9b62b03c30d74c2530e55714037bf0cf4", "parents": [ "1701f680407c6cc05121566cef5293d33881fe71" ], "author": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Fri Mar 25 14:37:32 2016 -0700" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Fri Mar 25 14:37:32 2016 -0700" }, "message": "[IA64] Enable preadv2 and pwritev2 syscalls for ia64\n\nNew system calls added in:\n f17d8b35452cab31a70d224964cd583fb2845449\n vfs: vfs: Define new syscalls preadv2,pwritev2\n\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "8e653b654497350f9cb3d6c2088207bc503f2c7c", "tree": "a50be8f3c775cef67021c68205a271836299d9f7", "parents": [ "f447671b9e4fa4b0c9faf39455269d62d94218ae" ], "author": { "name": "Rafael J.
