syz.1.315/8863 is trying to acquire lock:
ffff888031898770 (sb_internal#2){.+.+}-{0:0}, at: ocfs2_setattr+0xcc6/0x1cc0 fs/ocfs2/file.c:1270

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_internal#2 --> &oi->ip_xattr_sem --> &oi->ip_alloc_sem

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&oi->ip_alloc_sem);
