Does not work either, the /dev/userfaultfd was added without any changes in CONFIG. If we wanted this as generic funcitionality we would have to add .needs_devices field into tst_test structure but as far as I my grepping shows, usefaultfd is at the moment the only test that depends on a device that has been added recently so it does not look like it's worth the trouble. -- Cyril Hrubis chrubis@suse.cz -- Mailing list info: https://lists.linux.it/listinfo/ltp
