From: Robert P. J. Day Date: Tue, 29 Apr 2008 07:59:29 +0000 (-0700) Subject: lists: add "const" qualifier to first arg of list_splice() operations X-Git-Tag: v2.6.26-rc1~623 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=95d8c365b2df2adb904963333a93b15414403ed1;p=linux-2.6 lists: add "const" qualifier to first arg of list_splice() operations Since neither the list_splice() nor __list_splice() routines modify their first argument, might as well declare them "const".
