Hmm, I wasn't able to trigger it so easily, at least, while trying to
replicate Gary Hawco's, bug.  (Which also had Fix-EXT_MAX_BLOCK
applied.)  I wonder if he wasn't able to trigger it while doing the
partial rollback, and so ext4-fix-mb_find_next_bit-return.patch was
unfairly blamed for the BUG.

In any case, both patches have been pulled out of the patch series ,
and I'll release a new patchset until we can figure out what happened.

(Gary, this is why its important to get the kernel BUG/oops message;
it helps us correlate your bug reports with others.)
