X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f081a460bbac54c5ec460aac42079974ee413bd6;p=thirdparty%2Fkernel%2Flinux.git

selftests: mm: add shmem collapse as a default test item

Currently, we only test anonymous memory collapse by default.  We should
also add shmem collapse as a default test item to catch issues that could
break the test cases.
