hfsplus: invalid extended attribute record
============================================
WARNING: possible recursive locking detected
5.15.179-syzkaller #0 Not tainted
--------------------------------------------
syz.2.356/5747 is trying to acquire lock:
ffff888023be4b48 (&HFSPLUS_I(inode)->extents_lock){+.+.}-{3:3}, at: hfsplus_get_block+0x37f/0x14e0 fs/hfsplus/extents.c:260

but task is already holding lock:
ffff888023be5208 (&HFSPLUS_I(inode)->extents_lock){+.+.}-{3:3}, at: hfsplus_file_truncate+0x30f/0xc70 fs/hfsplus/extents.c:577

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
