[lxc-devel] [PATCH 1/4] Add missing 'extern' keyword to functions defined in cgroup.h

Hi,

Yes, but I personally think it's good practice to always put it there,
since it doesn't cause any harm either, because otherwise one may
forget the keyword with variables, where it really matters. Also, lxc
uses 'extern' throughout the rest of the code-base, so I see this part
of my patch as just harmonizing the file with coding standards of the
rest of the project.
