------------------------------------------------------
syz-executor.4/8330 is trying to acquire lock:
0000000079f7df20 (&p->lock){+.+.}, at: seq_read+0x71/0x1130 fs/seq_file.c:161
kobject: 'loop5' (000000002b0050e0): fill_kobj_path: path = '/devices/virtual/block/loop5'

but task is already holding lock:
00000000cec9e4b3 (&pipe->mutex/1){+.+.}, at: pipe_lock_nested fs/pipe.c:62 [inline]
00000000cec9e4b3 (&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:
