6.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Steven Rostedt (Google) <rostedt@xxxxxxxxxxx>
[ Upstream commit c049acee3c71cfc26c739f82617a84e13e471a45 ]
The function "scheduler_tick" was renamed to "sched_tick" and a selftest
that used that function for testing function trace filtering used that
function as part of the test.
But the change causes it to fail when run on older kernels. As tests
should not fail on older kernels, add a check to see which name is
available before testing.
Fixes: 86dd6c04ef9f ("sched/balancing: Rename scheduler_tick() => sched_tick()")
