Re: [PATCH] sched_ext: Fix several comment issues

Grepping the tree for the old spellings turns up exactly the lines you
touch and nothing else, and the new names hold up against what the
comments around them claim: __setscheduler_class() does return a
sched_class (kernel/sched/core.c:7608), task_should_scx() is reached from
it at 7617 and from the sched_fork() path at 4862, and the @running
callback documented at internal.h:439 is the one set_next_task_scx()
triggers.

One thing for the changelog rather than the diff: it lists three renames
while the patch fixes four sites, because __setschduler_prio and
__setscheduler_prio are two spellings of the same stale name.

Thanks,
