Release it to production!" :-) AFAIK, there's a test script from LTP does some mount namespace function and regression tests, e.g. --bind --make-private --make-shared --move $LTP_SOURCE/testscripts/test_fs_bind.sh And Zorro Lang has proposed some mount tests[1] for xfstests last May, but the tests never got reviewed & merged (hope they can be reviewed & committed by this opportunity :).
