I think this is a good idea, it makes code look saner.
I just did a search of list_for_each_entry_safe and found list_del is
usually(I didn't check every one of them) used before free.
So I'll add that in the next revision, probably some days later in case
there are other comments.
Thanks for your time to review the patch.
