WARNING: possible circular locking dependency detected

------------------------------------------------------
syz-executor5/27883 is trying to acquire lock:
000000005ad57224 (rlock-AF_UNIX){+.+.}, at: skb_queue_tail+0x26/0x150 net/core/skbuff.c:2968

but task is already holding lock:
00000000a92872cd (&(&u->lock)->rlock/1){+.+.}, at: unix_state_double_lock net/unix/af_unix.c:1085 [inline]
00000000a92872cd (&(&u->lock)->rlock/1){+.+.}, at: unix_state_double_lock+0x80/0xb0 net/unix/af_unix.c:1077

which lock already depends on the new lock.


the existing dependency chain (in reverse order) is:
