[v2 - now with correct cc list. Sorry for the dup, Linus]
Hi Linus,
Can you please pull the XFS fixes from the tag below? This is a fix
for a regression introduced in 4.5-rc1 by the new torn log write
detection code. The regression only affects people moving a clean
filesystem between machines/kernels of different architecture (such
as changing between 32 bit and 64 bit kernels), but this is the
recommended (and only!) safe way to migrate a filesystem between
architectures so we really need to ensure it works.
The changes are larger than I'd prefer right at the end of the
release cycle, but the majority of the change is just factoring
code to enable the detection of a clean log at the correct time to
avoid this issue.
Thanks!
-Dave.

xfs: only run torn log write detection on dirty logs (2016-03-07 08:22:22 +1100)
----------------------------------------------------------------
xfs: fixes for 4.5-rc7
Changes:
o Only perform torn log write detection on dirty logs. This prevents
failures being detected due to a clean filesystem being moved
between machines or kernels of different architectures (e.g. 32
-> 64 bit, BE -> LE, etc). This fixes a regression introduced by
the torn log write detection in 4.5-rc1.
----------------------------------------------------------------
Brian Foster (4):
xfs: separate log head record discovery from verification
xfs: refactor unmount record detection into helper
xfs: refactor in-core log state update to helper
xfs: only run torn log write detection on dirty logs
