LinuxSMB3 build backport
To view the list of patches which are included in the backports, see https://github.com/smfrench/smb3-backported-patches.git
To build the current (all relevant patches to cifs.ko that are accepted in mainline Linux, ie all CIFS/SMB3 fixes and features except those that are the result of global changes to the kernel or the VFS interface) cifs.ko:
git clone https://github.com/smfrench/smb3-cifs-linux-stable-backports.git
cd smb3-cifs-linux-stable-backports
[verify which branch you want to check out, which kernel you are trying to build]
cat /proc/version (to see what kernel you are running)
[if you do not have the kernel headers installed they can be downloaded e.g. from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D]
git branch (to see the cifs backport branches, currently 4.9 through 4.15)
git checkout 4.11-full-backport (as an example if you were trying to build for 4.11 kernel)
[verify that you are booted to a matching kernel version, in this case some version of 4.11 e.g. cat /proc/version]
cd fs/cifs
make C=1 -C /usr/src/Linux-headers-`uname-r` M=`pwd` modules
sudo modprobe cifs (if needed, e.g. to load any required loadable module dependencies for cifs.ko)
sudo rmmod cifs
sudo insmod ./cifs.ko (to load the module built a few steps above)
Enjoy ... (and test ... let us know on the mailing list if any problems)
