    selftests/mm: drop sys/dev test in uffd-stress test · 111fd29b
    Peter Xu authored
    With the new uffd unit test covering the /dev/userfaultfd path and syscall
    path of uffd initializations, we can safely drop the devnode test in the
    old stress test.
    
    One thing is to avoid duplication of running the stress test twice which is
    an overkill to only test the /dev/ interface in run_vmtests.sh.
    
    The other benefit is now all uffd tests (that uses userfaultfd_open) can
    run automatically as long as any type of interface is enabled (either
    syscall or dev), so it's more likely to succeed rather than fail due to
    unprivilege.
    
    With this patch lands, we can drop all the "mem_type:XXX" handlings too.
