syz.5.302/7494 is trying to acquire lock:
ffff88810a1dc708 (&HFSPLUS_I(inode)->extents_lock){+.+.}-{4:4}, at: hfsplus_get_block+0x39e/0x1670

but task is already holding lock:

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

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

 *** DEADLOCK ***

 May be due to missing lock nesting notation
