Subject: selftests/mm: run_vmtests.sh: don't gate THP and KSM tests on HAVE_HUGEPAGES
X-Git-Tag: v7.2-rc1~59^2~79
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=21de457215049aac93a8b0da1bba71c1a59d8be5;p=thirdparty%2Fkernel%2Flinux.git

selftests/mm: run_vmtests.sh: don't gate THP and KSM tests on HAVE_HUGEPAGES

HAVE_HUGEPAGES indicates availability of free HugeTLB pages.  It should
not be used to gate KSM test that merges transparent huge pages or
split_huge_page_test.

Remove check for HAVE_HUGEPAGES when running these tests.
