WARNING: possible circular locking dependency detected

------------------------------------------------------
syz-executor.3/17755 is trying to acquire lock:
000000006f5f0b27 (&acct->lock#2){+.+.}, at: acct_pin_kill+0x27/0x100 kernel/acct.c:173

but task is already holding lock:
000000005922399d (sb_writers#4){.+.+}, at: sb_start_write include/linux/fs.h:1569 [inline]
000000005922399d (sb_writers#4){.+.+}, at: mnt_want_write+0x3f/0xc0 fs/namespace.c:360

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:
  &acct->lock#2 --> &ovl_i_mutex_key[depth]#2 --> sb_writers#4

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(sb_writers#4);
