The patch titled Subject: kmod: add dependencies for test module has been added to the -mm tree. Its filename is kmod-add-test-driver-to-stress-test-the-module-loader-fix.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/kmod-add-test-driver-to-stress-test-the-module-loader-fix.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/kmod-add-test-driver-to-stress-test-the-module-loader-fix.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/SubmitChecklist when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Arnd Bergmann <arnd@xxxxxxxx> Subject: kmod: add dependencies for test module When we try to 'select' drivers whose dependencies are not met, we get a kconfig warning and undefined behavior as further 'select' statements in those drivers can not be honored: warning: (TEST_KMOD) selects TUN which has unmet direct dependencies (NETDEVICES && NET_CORE && INET) warning: (TEST_KMOD) selects XFS_FS which has unmet direct dependencies (BLOCK && (64BIT || LBDAF)) ERROR: "iomap_zero_range" [fs/xfs/xfs.ko] undefined! ERROR: "iomap_fiemap" [fs/xfs/xfs.ko] undefined! ERROR: "iomap_page_mkwrite" [fs/xfs/xfs.ko] undefined! To work around that, this adds the dependencies required by the 'tun', 'xfs' and 'btrfs' modules for CONFIG_TEST_KMOD, guaranteeing that we can always enable those, and fixing the 'randconfig' issues. Unfortunately, there is another problem that I have not found a good solution for: If any of the three drivers are built-in rather than loadable modules, then the module load test will later fail at runtime.
