Merge tag 'xfs-4.16-merge-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs updates from Darrick Wong:
"This merge cycle, we're again some substantive changes to XFS.

Metadata verifiers have been restructured to provide more detail about
which part of a metadata structure failed checks, and we've enhanced
the new online fsck feature to cross-reference extent allocation
information with the other metadata structures. With this pull, the
metadata verification part of online fsck is more or less finished,
though the feature is still experimental and still disabled by
default.

We're also preparing to remove the EXPERIMENTAL tag from a couple of
features this cycle. This week we're committing a bunch of space
accounting fixes for reflink and removing the EXPERIMENTAL tag from
reflink; I anticipate that we'll be ready to do the same for the
reverse mapping feature next week. (I don't have any pending fixes for
rmap; however I wish to remove the tags one at a time.)

This giant pile of patches has been run through a full xfstests run
over the weekend and through a quick xfstests run against this
morning's master, with no major failures reported. Let me know if
there's any merge problems -- git merge reported that one of our
patches touched the same function as the i_version series, but it
resolved things cleanly.

Summary:

- Log faulting code locations when verifiers fail, for improved
diagnosis of corrupt filesystems.

- Implement metadata verifiers for local format inode fork data.

- Online scrub now cross-references metadata records with other
metadata.

- Refactor the fs geometry ioctl generation functions.

- Harden various metadata verifiers.

- Fix various accounting problems.

- Fix uncancelled transactions leaking when xattr functions fail.

- Prevent the copy-on-write speculative preallocation garbage
collector from racing with writeback.

- Emit log reservation type information as trace data so that we can
compare against xfsprogs.

- Fix some erroneous asserts in the online scrub code.

- Clean up the transaction reservation calculations.

- Fix various minor bugs in online scrub.

- Log complaints about mixed dio/buffered writes once per day and
less noisily than before.

- Refactor buffer log item lists to use list_head.

- Break PNFS leases before reflinking blocks.

- Reduce lock contention on reflink source files.

- Fix some quota accounting problems with reflink.

- Fix a serious corruption problem in the direct cow write code where
we fed bad iomaps to the vfs iomap consumers.

- Various other refactorings.

- Remove EXPERIMENTAL tag from reflink!"

xfs: check btree block ownership with bnobt/rmapbt when scrubbing btree

When scanning a metadata btree block, cross-reference the block location
with the free space btree and the reverse mapping btree to ensure that
the rmapbt knows about the block and the bnobt does not. Add a
mechanism to defer checks when we happen to be scanning the bnobt/rmapbt
itself because it's less efficient to repeatedly clone and destroy the
cursor.

This patch provides the framework to make btree block owner checks
happen; the actual meat will be added in subsequent patches.
