WARNING: possible recursive locking detected

--------------------------------------------
syz-executor.1/11406 is trying to acquire lock:
 (&HFSPLUS_I(inode)->extents_lock){+.+.}, at: [<ffffffff81d2e069>] hfsplus_get_block+0x1f9/0x820 fs/hfsplus/extents.c:260

but task is already holding lock:
 (&HFSPLUS_I(inode)->extents_lock){+.+.}, at: [<ffffffff81d2d108>] hfsplus_file_extend+0x188/0xef0 fs/hfsplus/extents.c:452

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
