The patch titled
Subject: kmod: add dependencies for test module
has been removed from the -mm tree. Its filename was
kmod-add-test-driver-to-stress-test-the-module-loader-fix.patch
This patch was dropped because it was folded into kmod-add-test-driver-to-stress-test-the-module-loader.patch

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.
Fixes: ec159fed8677 ("kmod: add test driver to stress test the module loader")
