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. The fix is to take a
blocking inodelk on the subvols before starting rmdir.
Since selfheal requires lock on all subvols, if an rmdir
is in progess acquiring locks will fail and vice versa.
