From ff1f8ca0805ab03c31e14a9356aa2ac81d65c338 Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Fri, 4 Aug 2017 14:29:09 +0200 Subject: [PATCH] net: sched: cls_basic: no need to call tcf_exts_change for newly allocated struct As the f struct was allocated right before basic_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.
