WARNING: possible recursive locking detected
6.7.0-rc8-syzkaller-00101-g0802e17d9aca #0 Not tainted
--------------------------------------------
syz-executor.0/6549 is trying to acquire lock:
ffff0000d85260b0 (&tree->tree_lock/1){+.+.}-{3:3}, at: hfsplus_find_init+0x144/0x1bc

but task is already holding lock:
ffff0000d85260b0 (&tree->tree_lock/1){+.+.}-{3:3}, at: hfsplus_find_init+0x144/0x1bc

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

       CPU0
       ----
  lock(&tree->tree_lock/1);
  lock(&tree->tree_lock/1);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
