From 626ab0e69d376fa07599af669af8ba92d58e87c1 Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Fri, 23 Jun 2006 02:05:55 -0700 Subject: [PATCH] list: use list_replace_init() instead of list_splice_init() list_splice_init(list, head) does unneeded job if it is known that list_empty(head) == 1. We can use list_replace_init() instead. Signed-off-by: Oleg Nesterov Acked-by: David S.
