The comment and logic in xchk_btree_check_minrecs for dealing with
inode-rooted btrees isn't quite correct. While the direct children of
the inode root are allowed to have fewer records than what would
normally be allowed for a regular ondisk btree block, this is only true
if there is only one child block and the number of records don't fit in
the inode root.

Fix some serious WTF in the reference count scrubber's rmap fragment
processing. The code comment says that this loop is supposed to move
all fragment records starting at or before bno onto the worklist, but
there's no obvious reason why nr (the number of items added) should
increment starting from 1, and breaking the loop when we've added the
target number seems dubious since we could have more rmap fragments that
should have been added to the worklist.
This seems to manifest in xfs/411 when adding one to the refcount field.

The data fork scrubber calls filemap_write_and_wait to flush dirty pages
and delalloc reservations out to disk prior to checking the data fork's
extent mappings. Unfortunately, this means that scrub can consume the
EIO/ENOSPC errors that would otherwise have stayed around in the address
space until (we hope) the writer application calls fsync to persist data
and collect errors. The end result is that programs that wrote to a
file might never see the error code and proceed as if nothing were
wrong.
xfs_scrub is not in a position to notify file writers about the
writeback failure, and it's only here to check metadata, not file
contents. Therefore, if writeback fails, we should stuff the error code
back into the address space so that an fsync by the writer application
can pick that up.

These two things appear to be related. The assertion trips when another
thread initiates a fsmap request (which uses an empty transaction) after
the freezer waited for m_active_trans to hit zero but before the the
freezer executes the WARN_ON just prior to calling xfs_log_quiesce.
The lengthy delays in freezing happen because the freezer calls
xfs_wait_buftarg to clean out the buffer lru list. Meanwhile, the
GETFSMAP caller is continuing to grab and release buffers, which means
that it can take a very long time for the buffer lru list to empty out.
We fix both of these races by calling sb_start_write to obtain freeze
protection while using empty transactions for GETFSMAP and for metadata
scrubbing. The other two users occur during mount, during which time we
cannot fs freeze.

changed multiple levels of buffer pointers in the altpath structure.
Although we release the leaf level buffer, this isn't enough -- we also
need to release the node buffers that are unique to the altpath.
Not releasing all of the altpath buffers leaves them locked to the
transaction. This is suboptimal because we should release resources
when we don't need them anymore. Fix the function to loop all levels of

Pull xfs updates from Darrick Wong:
"In this release we clean out the last of the old 32-bit timestamp
code, fix a number of bugs and memory corruptions on 32-bit platforms,
and a refactoring of some of the extended attribute code.
I think I'll be back next week with some refactoring of how the XFS
buffer code returns error codes, however I prefer to hold onto that
for another week to let it soak a while longer
Summary:
- Get rid of compat_time_t
- Convert time_t to time64_t in quota code
- Remove shadow variables
- Prevent ATTR_ flag misuse in the attrmulti ioctls
- Clean out strlen in the attr code
- Remove some bogus asserts
- Fix various file size limit calculation errors with 32-bit kernels
- Pack xfs_dir2_sf_entry_t to fix build errors on arm oabi
- Fix nowait inode locking calls for directio aio reads
- Fix memory corruption bugs when invalidating remote xattr value
buffers
- Streamline remote attr value removal
- Make the buffer log format size consistent across platforms
- Strengthen buffer log format size checking
- Fix messed up return types of xfs_inode_need_cow
- Fix some unused variable warnings"

xfs: remove unused variable 'done'
xfs: fix uninitialized variable in xfs_attr3_leaf_inactive
xfs: change return value of xfs_inode_need_cow to int
xfs: check log iovec size to make sure it's plausibly a buffer log format
xfs: make struct xfs_buf_log_format have a consistent size
xfs: complain if anyone tries to create a too-large buffer log item
xfs: clean up xfs_buf_item_get_format return value
xfs: streamline xfs_attr3_leaf_inactive
xfs: fix memory corruption during remote attr value buffer invalidation
xfs: refactor remote attr value buffer invalidation
xfs: fix IOCB_NOWAIT handling in xfs_file_dio_aio_read
xfs: Add __packed to xfs_dir2_sf_entry_t definition
xfs: fix s_maxbytes computation on 32-bit kernels
xfs: truncate should remove all blocks, not just to the end of the page cache
xfs: introduce XFS_MAX_FILEOFF
xfs: remove bogus assertion when online repair isn't enabled
xfs: Remove all strlen in all xfs_attr_* functions for attr names.
xfs: fix misuse of the XFS_ATTR_INCOMPLETE flag
xfs: also remove cached ACLs when removing the underlying attr
xfs: reject invalid flags combinations in XFS_IOC_ATTRMULTI_BY_HANDLE
...
Drop the null buffer pointer checks in all code that calls
xfs_alloc_read_agf and doesn't pass XFS_ALLOC_FLAG_TRYLOCK because
they're no longer necessary.
