[PATCH 08/13] sched_ext: Make handle_lockup() propagate scx_verror() result
From: Tejun Heo
Date: Tue Nov 11 2025 - 14:18:26 EST
handle_lockup() currently calls scx_verror() but ignores its return value,
always returning true when the scheduler is enabled. Make it capture and return
the result from scx_verror(). This prepares for hardlockup handling.
