Put a new module at the end of the list intead of making new modules at the top of the list. find_module_all() start the hunt using the first entry on the list, if we assume that the modules which are first loaded are the most frequently looked for modules this should provide a tiny optimization. This is theoretical, and could use more actual data by analzying the impact of this patch on boot time a slew of systems using systemd-analyze. Signed-off-by: Luis R.
