Subject: selftests/mm: fix check for running THP tests
Date: Wed, 12 Feb 2025 17:44:25 +0000
When testing if we should try to compact memory or drop caches before we
run the THP or HugeTLB tests we use | as an or operator. This doesn't
work since run_vmtests.sh is written in shell where this is used to pipe
the output of the first argument into the second. Instead use the shell's
-o operator.
