[PATCH v5 00/12] xfstests: minor fixes for the reflink/dedupe tests

[Darrick J. Wong]

This is a patch set for xfstests, associated with the fifth revision
to a patch series adding reverse mapping and reflink to XFS.  Patches
1, 3-9, and 11 are bug fixes to existing reflink tests.

Patches 2 and 10 add a few more XFS-specific reflink tests to ensure
that we get the CoW and metadata reservation accounting correct.

Patch 12 adds tests for the new block device fallocate call; don't
bother merging it unless the corresponding kernel patches aren't
shouted down after a reasonable amount of time.

Comments and questions are, as always, welcome.  The fixes are
available on github[1].
