Problem fixed, thank. I'll do some tests.

Lockdep still detects this bug

[ INFO: possible circular locking dependency detected ]
events/0/8 is trying to acquire lock:
(memleak_lock){++..}, at: [<c0176a11>] memleak_free+0x9e/0x16f

but task is already holding lock:
(&parent->list_lock){++..}, at: [<c0174f29>] drain_array+0x49/0xad

which lock already depends on the new lock.
