 By the way, chunk-based files are all uncompressed for now.
 
+Long extended attribute name prefixes
+-------------------------------------
+There are use cases where extended attributes with different values can have
+only a few common prefixes (such as overlayfs xattrs).  The predefined prefixes
+work inefficiently in both image size and runtime performance in such cases.
+
+The long xattr name prefixes feature is introduced to address this issue.  The
+overall idea is that, apart from the existing predefined prefixes, the xattr
+entry could also refer to user-specified long xattr name prefixes, e.g.
+"trusted.overlay.".
+
+When referring to a long xattr name prefix, the highest bit (bit 7) of
+erofs_xattr_entry.e_name_index is set, while the lower bits (bit 0-6) as a whole
+represent the index of the referred long name prefix among all long name
+prefixes.  Therefore, only the trailing part of the name apart from the long
+xattr name prefix is stored in erofs_xattr_entry.e_name, which could be empty if
+the full xattr name matches exactly as its long xattr name prefix.
+
+All long xattr prefixes are stored one by one in the packed inode as long as
+the packed inode is valid, or in the meta inode otherwise.  The
+xattr_prefix_count (of the on-disk superblock) indicates the total number of
+long xattr name prefixes, while (xattr_prefix_start * 4) indicates the start
+offset of long name prefixes in the packed/meta inode.  Note that, long extended
+attribute name prefixes are disabled if xattr_prefix_count is 0.
+
+Each long name prefix is stored in the format: ALIGN({__le16 len, data}, 4),
+where len represents the total size of the data part.  The data part is actually
+represented by 'struct erofs_xattr_long_prefix', where base_index represents the
+index of the predefined xattr name prefix, e.g. EROFS_XATTR_INDEX_TRUSTED for
+"trusted.overlay." long name prefix, while the infix string keeps the string
+after stripping the short prefix, e.g. "overlay." for the example above.

+The order of opening block devices and matching or creating superblocks has
+changed.
+
+The old logic opened block devices first and then tried to find a
+suitable superblock to reuse based on the block device pointer.
+
+The new logic tries to find a suitable superblock first based on the device
+number, and opening the block device afterwards.
+
+Since opening block devices cannot happen under s_umount because of lock
+ordering requirements s_umount is now dropped while opening block devices and
+reacquired before calling fill_super().
+
+In the old logic concurrent mounters would find the superblock on the list of
+superblocks for the filesystem type. Since the first opener of the block device
+would hold s_umount they would wait until the superblock became either born or
+was discarded due to initialization failure.
+
+Since the new logic drops s_umount concurrent mounters could grab s_umount and
+would spin. Instead they are now made to wait using an explicit wait-wake
+mechanism without having to hold s_umount.
+
+---
+
+**mandatory**
+
+The holder of a block device is now the superblock.
+
+The holder of a block device used to be the file_system_type which wasn't
+particularly useful. It wasn't possible to go from block device to owning
+superblock without matching on the device pointer stored in the superblock.
+This mechanism would only work for a single device so the block layer couldn't
+find the owning superblock of any additional devices.
+
+In the old mechanism reusing or creating a superblock for a racing mount(2) and
+umount(2) relied on the file_system_type as the holder. This was severly
+underdocumented however:
+
+(1) Any concurrent mounter that managed to grab an active reference on an
+    existing superblock was made to wait until the superblock either became
+    ready or until the superblock was removed from the list of superblocks of
+    the filesystem type. If the superblock is ready the caller would simple
+    reuse it.
+
+(2) If the mounter came after deactivate_locked_super() but before
+    the superblock had been removed from the list of superblocks of the
+    filesystem type the mounter would wait until the superblock was shutdown,
+    reuse the block device and allocate a new superblock.
+
+(3) If the mounter came after deactivate_locked_super() and after
+    the superblock had been removed from the list of superblocks of the
+    filesystem type the mounter would reuse the block device and allocate a new
+    superblock (the bd_holder point may still be set to the filesystem type).
+
+Because the holder of the block device was the file_system_type any concurrent
+mounter could open the block devices of any superblock of the same
+file_system_type without risking seeing EBUSY because the block device was
+still in use by another superblock.
+
+Making the superblock the owner of the block device changes this as the holder
+is now a unique superblock and thus block devices associated with it cannot be
+reused by concurrent mounters. So a concurrent mounter in (2) could suddenly
+see EBUSY when trying to open a block device whose holder was a different
+superblock.
+
+The new logic thus waits until the superblock and the devices are shutdown in
+->kill_sb(). Removal of the superblock from the list of superblocks of the
+filesystem type is now moved to a later point when the devices are closed:
+
+(1) Any concurrent mounter managing to grab an active reference on an existing
+    superblock is made to wait until the superblock is either ready or until
+    the superblock and all devices are shutdown in ->kill_sb(). If the
+    superblock is ready the caller will simply reuse it.
+
+(2) If the mounter comes after deactivate_locked_super() but before
+    the superblock has been removed from the list of superblocks of the
+    filesystem type the mounter is made to wait until the superblock and the
+    devices are shut down in ->kill_sb() and the superblock is removed from the
+    list of superblocks of the filesystem type. The mounter will allocate a new
+    superblock and grab ownership of the block device (the bd_holder pointer of
+    the block device will be set to the newly allocated superblock).
+
+(3) This case is now collapsed into (2) as the superblock is left on the list
+    of superblocks of the filesystem type until all devices are shutdown in
+    ->kill_sb(). In other words, if the superblock isn't on the list of
+    superblock of the filesystem type anymore then it has given up ownership of
+    all associated block devices (the bd_holder pointer is NULL).
+
+As this is a VFS level change it has no practical consequences for filesystems
+other than that all of them must use one of the provided kill_litter_super(),
+kill_anon_super(), or kill_block_super() helpers.

+Optional dependencies
+~~~~~~~~~~~~~~~~~~~~~
+
+Some drivers are able to optionally use a feature from another module
+or build cleanly with that module disabled, but cause a link failure
+when trying to use that loadable module from a built-in driver.
+
+The most common way to express this optional dependency in Kconfig logic
+uses the slightly counterintuitive::
+
+  config FOO
+	tristate "Support for foo hardware"
+	depends on BAR || !BAR
+
+This means that there is either a dependency on BAR that disallows
+the combination of FOO=y with BAR=m, or BAR is completely disabled.
+For a more formalized approach if there are multiple drivers that have
+the same dependency, a helper symbol can be used, like::
+
+  config FOO
+	tristate "Support for foo hardware"
+	depends on BAR_OPTIONAL

+ * We need to walk the filesystem free space and issue discards on the free
+ * space that meet the search criteria (size and location). We cannot issue
+ * discards on extents that might be in use, or are so recently in use they are
+ * still marked as busy. To serialise against extent state changes whilst we are
+ * gathering extents to trim, we must hold the AGF lock to lock out other
+ * allocations and extent free operations that might change extent state.
+ *
+ * However, we cannot just hold the AGF for the entire AG free space walk whilst
+ * we issue discards on each free space that is found. Storage devices can have
+ * extremely slow discard implementations (e.g. ceph RBD) and so walking a
+ * couple of million free extents and issuing synchronous discards on each
+ * extent can take a *long* time. Whilst we are doing this walk, nothing else
+ * can access the AGF, and we can stall transactions and hence the log whilst
+ * modifications wait for the AGF lock to be released. This can lead hung tasks
+ * kicking the hung task timer and rebooting the system. This is bad.
+ *
+ * Hence we need to take a leaf from the bulkstat playbook. It takes the AGI
+ * lock, gathers a range of inode cluster buffers that are allocated, drops the
+ * AGI lock and then reads all the inode cluster buffers and processes them. It
+ * loops doing this, using a cursor to keep track of where it is up to in the AG
+ * for each iteration to restart the INOBT lookup from.
+ *
+ * We can't do this exactly with free space - once we drop the AGF lock, the
+ * state of the free extent is out of our control and we cannot run a discard
+ * safely on it in this situation. Unless, of course, we've marked the free
+ * extent as busy and undergoing a discard operation whilst we held the AGF
+ * locked.
+ *
+ * This is exactly how online discard works - free extents are marked busy when
+ * they are freed, and once the extent free has been committed to the journal,
+ * the busy extent record is marked as "undergoing discard" and the discard is
+ * then issued on the free extent. Once the discard completes, the busy extent
+ * record is removed and the extent is able to be allocated again.
+ *
+ * In the context of fstrim, if we find a free extent we need to discard, we
+ * don't have to discard it immediately. All we need to do it record that free
+ * extent as being busy and under discard, and all the allocation routines will
+ * now avoid trying to allocate it. Hence if we mark the extent as busy under
+ * the AGF lock, we can safely discard it without holding the AGF lock because
+ * nothing will attempt to allocate that free space until the discard completes.
+ *
+ * This also allows us to issue discards asynchronously like we do with online
+ * discard, and so for fast devices fstrim will run much faster as we can have
+ * multiple discard operations in flight at once, as well as pipeline the free
+ * extent search so that it overlaps in flight discard IO.
