WARNING: possible circular locking dependency detected

------------------------------------------------------
syz-executor.5/8182 is trying to acquire lock:
00000000673981b7 (&p->lock){+.+.}, at: seq_read+0x71/0x1130 fs/seq_file.c:161

but task is already holding lock:
000000007c62e35b (&pipe->mutex/1){+.+.}, at: pipe_lock_nested fs/pipe.c:62 [inline]
000000007c62e35b (&pipe->mutex/1){+.+.}, at: pipe_lock+0x6e/0x80 fs/pipe.c:70

which lock already depends on the new lock.


the existing dependency chain (in reverse order) is:

other info that might help us debug this:

Chain exists of:
  &p->lock --> &sig->cred_guard_mutex --> &pipe->mutex/1

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&pipe->mutex/1);
                               lock(&sig->cred_guard_mutex);
                               lock(&pipe->mutex/1);
  lock(&p->lock);
