v2: 1) fixed silly usage of template cache as a real one (this code left from static global cache for all) This patch makes unix_gid_cache cache detail allocated and registered per network namespace context. Thus with this patch unix_gid_cache contents for network namespace "X" are controlled from proc file system mount for the same network namespace "X".
