syz-executor0/27385 is trying to acquire lock:
00000000d0ec020c (&acct->lock#2){+.+.}, at: acct_pin_kill+0x26/0x100

but task is already holding lock:

00000000dea1d1e8 (sb_writers#5){.+.+}, at: mnt_want_write+0x3f/0xc0

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] --> sb_writers#5

  Possible unsafe locking scenario:
