Thanks! However it looks like we cannot do that, the /dev/userfaultfd was added into 6.1 while the usefaultfd syscall existed since 4.3. Hence tests that need /dev/userfaultfd need additional checks. However it may be a good idea to add .needs_kconfig to all the userfaultfd tests we have. -- Cyril Hrubis chrubis@suse.cz -- Mailing list info: https://lists.linux.it/listinfo/ltp
