It is a quite extensive FS check which we use for UBIFS. As UBIFS is the
main UBI client - it makes sense to run it. It lives in the
mtd-utils.git/tests/fs/integck

./integck -n8 /mnt/ubifs

would run in. /mnt/ubifs is the ubifs mount-point. -n8 means repeat 8
times.

Cool!

Yes, it would be great to integrate this, of course. I might also want
to send you a patch, then I'd run it.
