Reiser4 bug?
=======================================================
[ INFO: possible circular locking dependency detected ]
2.6.18-rc4-mm2 #106
-------------------------------------------------------
umount/2571 is trying to acquire lock:
(&txnh->hlock){--..}, at: [<fe60590d>] commit_txnh+0x3a/0xad [reiser4]
but task is already holding lock:
(&atom->alock){--..}, at: [<fe604467>] txnh_get_atom+0x1c/0x78 [reiser4]
which lock already depends on the new lock.
the existing dependency chain (in reverse order) is:
