From 7d283aee50351ec19eaf654a8690d77c4e1dff50 Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Wed, 6 Aug 2008 15:21:26 -0700 Subject: list.h: Add list_splice_tail() and list_splice_tail_init() If you are using linked lists for queues list_splice() will not do what you would expect even if you use the elements passed reversed. We need to handle these differently. We add list_splice_tail() and list_splice_tail_init(). Signed-off-by: Peter Zijlstra Signed-off-by: Luis R. Rodriguez Signed-off-by: John W.
