This patchset depends on the following fix which is being sent separately targeting sched_ext/for-7.0-fixes: http://lkml.kernel.org/r/20260225050055.1069822-1-tj@kernel.org sched_ext: Disable preemption between scx_claim_exit() and kicking helper work - #6 updated to preserve preempt guard in the rewritten scx_disable(). - #9: Fixed BTF_ID_FLAGS for scx_bpf_locked_rq - comma between KF_IMPLICIT_ARGS and KF_RET_NULL should be bitwise OR. - #15: Added NULL check for sch in scx_bypass() to fix NULL deref when PM notifier calls scx_bypass() with no scheduler loaded. - #29: Fixed scx_fail_parent() call to pass sch instead of parent, avoiding NULL deref when disabling a level-1 sub-sched. v1: http://lkml.kernel.org/r/20260121231140.832332-1-tj@kernel.org Thanks. -- tejun
