Subject: [PATCH 6.12] Revert "selftests/sched_ext: fix build after renames in sched_ext API"
This reverts commit fc20e87419e59d86f3bbcee2d4506bcd01c6450a.
Commit "selftests/sched_ext: fix build after renames in sched_ext API”
was pulled into 6.12.y without the sched_ext API renames it depends on.
The prereqs can be found in
https://lore.kernel.org/lkml/20241110200308.103681-1-tj@kernel.org/
As a result, sched_ext selftests fail to compile.
Cc: stable@...r.kernel.org
Fixes: fc20e87419e59 ("selftests/sched_ext: fix build after renames in sched_ext API")
Signed-off-by: Libo Chen <libo.chen@...cle.com>
