There is actually a file-system subsys - look up for fs_subsys. It is
declared at fs/namespace.c.
Further down the patch you'll see:
+ kset_set_kset_s(&jffs2_subsys, fs_subsys);
There was a reason for doing that instead using fs_subsys in the above
although I can't remember why offhand. I did try it and it didn't work
as expected...
