+1 on the change:

$ git remote -v
origin git://git.kernel.org/pub/scm/docs/man-pages/man-pages.git (fetch)
origin git://git.kernel.org/pub/scm/docs/man-pages/man-pages.git (push)
$ git describe
man-pages-4.06-441-gaa30354
$ git grep -i 'file.system' | wc -l
36
$ git grep -i 'filesystem' | wc -l
879

But you're missing some instances from runtime-spec:

$ git remote -v | grep origin
origin git://github.com/opencontainers/runtime-spec.git (fetch)
origin git://github.com/opencontainers/runtime-spec.git (push)
$ git describe origin/pr/529
v1.0.0-rc1-48-g6c3d2e6
$ git grep -i 'file.system' origin/pr/529 | wc -l
2
$ git grep -i 'file.system' origin/pr/529
origin/pr/529:config-linux.md:The Linux container specification uses various kernel features like namespaces, cgroups, capabilities, LSM, and file system jails to fulfill the spec.
