[PATCH v2 0/3] xfs: miscellaneous log recovery fixes

[Brian Foster <bfoster@redhat.com>]

Hi all,

Here's v2 of the log recovery fixups for filesystems with undersized
logs and the v4 NULL buffer verifier problem. The most significant
change is that patch 1 is rewritten to take a different approach to
sanity check the log block addresses used during log recovery cycle and
record verification. Specifically, it validates the log block number
used for each buffer on read or write. Also, I've dropped patch 4 for
now since I've not heard anything to suggest it's really necessary.

v2:
- Use xlog buffer validation rather than explicit checks.
- Don't push AIL on log recovery error.
- Drop patch 4 (rfc).
- Fix up commit logs.
