From 5e1ad95b630e652d3467d1fd1f0b5e5ea2c441e2 Mon Sep 17 00:00:00 2001 From: Vlad Buslov Date: Wed, 30 Oct 2019 16:09:01 +0200 Subject: [PATCH] net: sched: extract bstats update code into function Extract common code that increments cpu_bstats counter into standalone act API function. Change hardware offloaded actions that use percpu counter allocation to use the new function instead of incrementing cpu_bstats directly. This commit doesn't change functionality.
