syz-executor1/26979 is trying to acquire lock:
00000000ea30848a (&sig->cred_guard_mutex){+.+.}, at: do_io_accounting+0x1d1/0xfe0 fs/proc/base.c:2711

but task is already holding lock:
0000000085644f34 (&p->lock){+.+.}, at: seq_read+0x71/0x1130 fs/seq_file.c:161

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:
  &sig->cred_guard_mutex --> sb_writers#3 --> &p->lock

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&p->lock);
                               lock(sb_writers#3);
                               lock(&p->lock);
  lock(&sig->cred_guard_mutex);
