From: Jie Liu <jeff.liu@xxxxxxxxxx>
At xfs_ail_min(), we do check if the AIL list is empty or not before
returning the first item in it with list_empty() and list_first_entry().
This can be simplified a bit with a new list operation routine that is
the list_first_entry_or_null() which has been introduced by:
commit 6d7581e62f8be462440d7b22c6361f7c9fa4902b
list: introduce list_first_entry_or_null
