dht: lock on subvols to prevent lookup vs rmdir race
There is a possibility that while an rmdir is completed on
some non-hashed subvol and proceeding to others, a lookup
selfheal can recreate the same directory on those subvols
for which the rmdir had succeeded. Now the deletion of the
parent directory will fail with an ENOTEMPTY.
To fix this take blocking inodelk on the subvols before
starting rmdir. Selfheal must also take blocking inodelk
before creating the entry.
