From db4b49025c0c7116f1d2dfe8d5bbfc983ac054de Mon Sep 17 00:00:00 2001 From: Paul Blakey Date: Sat, 18 Feb 2023 00:36:13 +0200 Subject: [PATCH] net/sched: Rename user cookie and act cookie struct tc_action->act_cookie is a user defined cookie, and the related struct flow_action_entry->act_cookie is used as an handle similar to struct flow_cls_offload->cookie. Rename tc_action->act_cookie to user_cookie, and flow_action_entry->act_cookie to cookie so their names would better fit their usage.
