[Qemu-devel] [PATCH] exec: silence hugetlbfs warning under qtest

[marcandre.lureau@redhat.com]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

vhost-user-test prints a warning. A test should not need to run on
hugetlbfs, let's silence the warning under qtest. Unfortunately, the
condition can't check on qtest_enabled() or qtest_driver() since they
are initialized later.
