syz.0.17/5921 is trying to acquire lock:
ffff888022716460 (sb_writers#12){.+.+}-{0:0}, at: lookup_open+0x150/0x1990 fs/namei.c:4451

other info that might help us debug this:
 Possible unsafe locking scenario:

       ----
  lock(sb_writers#12);
  lock(sb_writers#12);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
