From: Jiri Pirko Date: Fri, 4 Aug 2017 12:29:08 +0000 (+0200) Subject: net: sched: cls_matchall: no need to call tcf_exts_change for newly allocated struct X-Git-Tag: v4.14-rc1~130^2~373^2~7 X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=a74cb36980c3676c888a87dd66bcd410f7e75c08;p=uclinux-h8%2Flinux.git net: sched: cls_matchall: no need to call tcf_exts_change for newly allocated struct As the head struct was allocated right before mall_set_parms call, no need to use tcf_exts_change to do atomic change, and we can just fill-up the unused exts struct directly by tcf_exts_validate.
