Subject: selftests/vm: run_vmtest.sh: update and clean up gup_test invocation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Run benchmarks on the _fast variants of gup and pup, as originally
intended.

Run the new gup_test sub-test: dump pages.  In addition to exercising the
dump_page() call, it also demonstrates the various options you can use to
specify which pages to dump, and how.
