Subject: [PATCH 5.10 438/452] kseltest/cgroup: Make test_stress.sh work if run interactively

From: Waiman Long <longman@...hat.com>

commit 213adc63dfbcdff9a0c19ec1f2681fda9c05cf6d upstream.

Commit 54de76c01239 ("kselftest/cgroup: fix test_stress.sh to use OUTPUT
dir") changes the test_core command path from . to $OUTPUT. However,
variable OUTPUT may not be defined if the command is run interactively.
Fix that by using ${OUTPUT:-.} to cover both cases.
