From 8076428f0c9f24d90270204fd39ccb11b83db71d Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 11 Sep 2017 11:24:22 +0200 Subject: [PATCH] s390: convert release_thread() into a static inline function release_thread() is an empty function that gets called on every task exit. Move the function to a header file and force inlining of it, so that the compiler can optimize it away instead of generating a pointless function call.
