WARNING: possible recursive locking detected
5.15.174-syzkaller #0 Not tainted
--------------------------------------------
syz-executor.0/4570 is trying to acquire lock:
ffff88806ef31548 (&HFSPLUS_I(inode)->extents_lock){+.+.}-{3:3}, at: hfsplus_get_block+0x37f/0x14e0 fs/hfsplus/extents.c:260

but task is already holding lock:

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

       CPU0
       ----
  lock(&HFSPLUS_I(inode)->extents_lock);
  lock(&HFSPLUS_I(inode)->extents_lock);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
