Re: [PATCHSET v2 sched_ext/for-7.1] sched_ext: Implement cgroup sub-scheduler support

[Tejun Heo]

Correctly noting the changes from v1 which I forgot to include in the
cover letter.

v2: Rebased to sched_ext/for-7.1. 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@xxxxxxxxxx
      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@xxxxxxxxxx

Thanks.
