Pull xfs updates from Chandan Babu:
"Online repair feature continues to be expanded. Also, we now support
delayed allocation for realtime devices which have an extent size that
is equal to filesystem's block size.

New code:

- Introduce Parent Pointer extended attribute for inodes

- Bring back delalloc support for realtime devices which have an
extent size that is equal to filesystem's block size

- Improve performance of log incompat feature handling

Online Repair:

- Implement atomic file content exchanges i.e. exchange ranges of
bytes between two files atomically

- Create temporary files to repair file-based metadata. This uses
atomic file content exchange facility to swap file fork mappings
between the temporary file and the metadata inode

- Allow callers of directory/xattr code to set an explicit owner
number to be written into the header fields of any new blocks that
are created. This is required to avoid walking every block of the
new structure and modify their ownership during online repair

- Repair more data structures:
- Extended attributes
- Inode unlinked state
- Directories
- Symbolic links
- AGI's unlinked inode list
- Parent pointers

- Move Orphan files to lost and found directory

- Fixes for Inode repair functionality

- Introduce a new sub-AG FITRIM implementation to reduce the duration
for which the AGF lock is held

- Updates for the design documentation

- Use Parent Pointers to assist in checking directories, parent
pointers, extended attributes, and link counts

Fixes:

- Prevent userspace from reading invalid file data due to incorrect.
updation of file size when performing a non-atomic clone operation

- Minor fixes to online repair

- Fix confusing return values from xfs_bmapi_write()

- Fix an out of bounds access due to incorrect h_size during log
recovery

- Defer upgrading the extent counters in xfs_reflink_end_cow_extent()
until we know we are going to modify the extent mapping

- Remove racy access to if_bytes check in
xfs_reflink_end_cow_extent()

- Fix sparse warnings

Cleanups:

- Hold inode locks on all files involved in a rename until the
completion of the operation. This is in preparation for the parent
pointers patchset where parent pointers are applied in a separate
chained update from the actual directory update

- Compile out v4 support when disabled

- Cleanup xfs_extent_busy_clear()

- Remove unused flags and fields from struct xfs_da_args

- Remove definitions of unused functions

- Improve extended attribute validation

- Add higher level directory operations helpers to remove duplication
of code

- Cleanup quota (un)reservation interfaces"

xfs: detect and correct directory tree problems

Historically, checking the tree-ness of the directory tree structure has
not been complete. Cycles of subdirectories break the tree properties,
as do subdirectories with multiple parents. It's easy enough for DFS to
detect problems as long as one of the participants is reachable from the
root, but this technique cannot find unconnected cycles.

Directory parent pointers change that, because we can discover all of
these problems from a simple walk from a subdirectory towards the root.
For each child we start with, if the walk terminates without reaching
the root, we know the path is disconnected and ought to be attached to
the lost and found. If we find ourselves, we know this is a cycle and
can delete an incoming edge. If we find multiple paths to the root, we
know to delete an incoming edge.

Even better, once we've finished walking paths, we've identified the
good ones and know which other path(s) to remove.

xfs: online repair for parent pointers

This series implements online repair for directory parent pointer
metadata. The checking half is fairly straightforward -- for each
outgoing directory link (forward or backwards), grab the inode at the
other end, and confirm that there's a corresponding link. If we can't
grab an inode or lock it, we'll save that link for a slower loop that
cycles all the locks, confirms the continued existence of the link, and
rechecks the link if it's actually still there.

Repairs are a bit more involved -- for directories, we walk the entire
filesystem to rebuild the dirents from parent pointer information.
Parent pointer repairs do the same walk but rebuild the pptrs from the
dirent information, but with the added twist that it duplicates all the
xattrs so that it can use the atomic extent swapping code to commit the
repairs atomically.

This introduces an added twist to the xattr repair code -- we use dirent
hooks to detect a colliding update to the pptr data while we're not
holding the ILOCKs; if one is detected, we restart the xattr salvaging
process but this time hold all the ILOCKs until the end of the scan.

For offline repair, the phase6 directory connectivity scan generates an
index of all the expected parent pointers in the filesystem. Then it
walks each file and compares the parent pointers attached to that file
against the index generated, and resyncs the results as necessary.

xfs: Parent Pointers

This is the latest parent pointer attributes for xfs. The goal of this
patch set is to add a parent pointer attribute to each inode. The
attribute name containing the parent inode, generation, and directory
offset, while the attribute value contains the file name. This feature
will enable future optimizations for online scrub, shrink, nfs handles,
verity, or any other feature that could make use of quickly deriving an
inodes path from the mount point.

Directory parent pointers are stored as namespaced extended attributes
of a file. Because parent pointers are an indivisible tuple of
(dirent_name, parent_ino, parent_gen) we cannot use the usual attr name
lookup functions to find a parent pointer. This is solvable by
introducing a new lookup mode that checks both the name and the value of
the xattr.

Therefore, introduce this new name-value lookup mode that's gated on the
XFS_ATTR_PARENT namespace. This requires the introduction of new
opcodes for the extended attribute update log intent items, which
actually means that parent pointers (itself an INCOMPAT feature) does
not depend on the LOGGED_XATTRS log incompat feature bit.

To reduce collisions on the dirent names of parent pointers, introduce a
new attr hash mode that is the dir2 namehash of the dirent name xor'd
with the parent inode number.

xfs: move orphan files to lost and found

Orphaned files are defined to be files with nonzero ondisk link count
but no observable parent directory. This series enables online repair
to reparent orphaned files into the filesystem directory tree, and wires
up this reparenting ability into the directory, file link count, and
parent pointer repair functions. This is how we fix files with positive
link count that are not reachable through the directory tree.

This patch will also create the orphanage directory (lost+found) if it
is not present. In contrast to xfs_repair, we follow e2fsck in creating
the lost+found without group or other-owner access to avoid accidental
disclosure of files that were previously hidden by an 0700 directory.
That's silly security, but people have been known to do it.
