From 21cb84c48ca0619181106f0f44f3802a989de024 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Tue, 15 Nov 2016 10:15:12 -0800 Subject: [PATCH] net: busy-poll: remove need_resched() from sk_can_busy_loop() Now sk_busy_loop() can schedule by itself, we can remove need_resched() check from sk_can_busy_loop() Also add a const to its struct sock parameter.
