wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# install riscv cross compiling tool for clang build
# apt-get install binutils-riscv64-linux-gnu
git remote add cifs git://git.samba.org/sfrench/cifs-2.6.git
git fetch --no-tags cifs for-next
git checkout 2494367d9d48498364276355dd85825c967d63c6
# save the attached .config to linux build tree

Note: the cifs/for-next HEAD de1ecd1edc1c428e6b1b37a0557d13ba7473e4fb builds fine.
It only hurts bisectibility.
