Can you please remind me of the use case that requires this ? I browsed
through
related mails in the past but haven't found when is that needed. For amdgpu
drm_sched_job_init and drm_sched_job_arm are called together and amdgpu
is the only one who supports modifying entity priority on the fly as far
as i see.

We already discussed that the call to drm_sched_entity_select_rq() needs
to move to drm_sched_job_arm() to be able to set a new scheduler list
between _init() and _arm(). This was just not applied for some reason.
