I think you misread this cleanup. Or may be I misunderstood you...

The patch only removes the unnecessary INIT_LIST_HEAD/list_del and
changes the code to use list_for_each_entry (_safe is not needed).

list_add() doesn't need the initialized entry, and there is no need
to "cleanup" ->pending_list after list_for_each().

However. If you dislike this change, feel free to nack it.. Cleanups
are always subjective, I won't argue if you prefer the current code.

Oleg.
