That could be the race condition I was trying to track down in the ext2fs code
for some time (it is also derived from FFS). Quite hard to find, as this panic
is really unfrequent on my boxes. I'll have a look deeper about that.
If you commit this, could you call the functions ufs_* rather than ffs_*, and
place them in a file where ext2fs could also use them ?
