From 25c411fce735dda29de26f58d3fce52d4824380c Mon Sep 17 00:00:00 2001 From: John Stultz Date: Sat, 12 Jul 2025 03:33:42 +0000 Subject: sched: Add CONFIG_SCHED_PROXY_EXEC & boot argument to enable/disable Add a CONFIG_SCHED_PROXY_EXEC option, along with a boot argument sched_proxy_exec= that can be used to disable the feature at boot time if CONFIG_SCHED_PROXY_EXEC was enabled. Also uses this option to allow the rq->donor to be different from rq->curr.
