From: fangqiurong Date: Fri, 3 Apr 2026 05:58:06 +0000 (+0800) Subject: sched/doc: Update yield_task description in sched-design-CFS X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1cc973b7c94a77bd3419bca847bbf19b5cfdfa4c;p=thirdparty%2Fkernel%2Flinux.git sched/doc: Update yield_task description in sched-design-CFS The yield_task description referenced the long-removed compat_yield sysctl and described the function as a dequeue/enqueue cycle. Update it to reflect current behavior: yielding the CPU by moving the current task's position back in the runqueue. Sync zh_CN and sp_SP translations.
