Subject: llist: llist_add() can use llist_add_batch()
X-Git-Tag: v3.11-rc1~2^2~7
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e9a17bd73a29e5323c37ec5ffe50fc0e825d3d03;p=pandora-kernel.git

llist: llist_add() can use llist_add_batch()

llist_add(new, head) can simply use llist_add_batch(new, new, head),
no need to duplicate the code.

This obviously uninlines llist_add() and to me this is a win. But we
can make llist_add_batch() inline if this is desirable, in this case
gcc can notice that new_first == new_last if the caller is llist_add().
