[PATCHv3 1/3] list: Use argument hlist_add_after names from rcu variant

[Ken Helias]

From: Ken Helias <kenhelias@xxxxxxxxxxx>

The argument names of the hlist_add_after are poorly chosen because they look
the same as the ones from hlist_add_before but have to be used completely
different. This easily confuses the reader. The creator of the
hlist_add_after_rcu function has made a lot better choice.

v2:
Splitted into two patches

The patches to add list_add_before/behind were removed because it seems that
there is a consensus that list_add is understood by everyone automatically
as list_add_behind and list_add_tail is understood by everyone as
list_add_before.... even when the names suggest otherwise.
