From 13c2235b2b2870675195f0b551275d1abdd81068 Mon Sep 17 00:00:00 2001 From: Edmundo Carmona Antoranz Date: Sat, 6 Mar 2021 15:07:39 -0600 Subject: [PATCH] sched: Remove unnecessary variable from schedule_tail() Since 565790d28b1 (sched: Fix balance_callback(), 2020-05-11), there is no longer a need to reuse the result value of the call to finish_task_switch() inside schedule_tail(), therefore the variable used to hold that value (rq) is no longer needed.
