So in debugging mysterious 'lockups' where I've, at least once,
noticed a
hangcheck_timer elapse, this lock-checking stuff is just nonsensical?
It is very
frustrating trying to turn on debug tools in the kernel and get so many
false positives.
Would it be possible or, perhaps, desirable to eliminate the buggy
lock-checks in the
xfs code?
Meanwhile...back to finding reasons for the semi-random, periodic hanging...
