| |
Hi Folks,
This patch is trying to introduce a new list helper to retrieve the last entry or return NULL if the list is empty corresponding to it, which is inspired by Jiri Pirko's list_first_entry_or_null().
With this trivial helper, we could get a little benefit to simplify the code logic of xfs_ail_max() and make the code looks a bit more consistent with xfs_ail_min() which has already been simplified via list_first_entry_or_null().
Moreover, as a per simple grep against fs as well as driver's tree, I think there are some other places could make use of it for similar purpose, here I spread this helper over some file systems as well.
Any comments are welcome!
Thanks, -Jeff
