syz-executor.4/20130 is trying to acquire lock:

00000000d7d9361e (&sbi->lock){+.+.}, at: reiserfs_write_lock+0x75/0xf0 fs/reiserfs/lock.c:27

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:
  sb_writers#16 --> &type->i_mutex_dir_key#9 --> &sbi->lock

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&sbi->lock);
