Subject: [Cluster-devel] [PATCH 0/6] list: introduce list_last_entry_or_null()
Date: Fri, 15 Nov 2013 12:29:48 +0800 [thread overview]
Message-ID: <5285A33C.4040808@oracle.com> (raw)
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
