Just for XFs list folks:

I'm not sure why XFS would cause this - the crash is outside XFS releasing
a mutex (sb->s_lock) that XFS code has never touched. I doubt anyone
in the XFS team has done any testing on this -mm kernel...

What is the test case, Michal? Can you post the script you used?

Cheers,

Dave.
