The test selection code in mmap_sanity.c could be modified to share the new test selection infrastructure added in llapi_test_util.c from patch https://review.whamcloud.com/58786 ("LU-15762 tests: skip llapi_hsm_test113 on old server").

Some small changes would be needed in llapi_test_util.c to pass the Lustre mountpoint as an argument to the test function (as mmap_sanity.c does) instead of accessing it via a global variable, but this seems like a net improvement. Other than this, the code seems fairly similar (except to allow -e as an alias of -s) and looks like it could easily be shared.
