[PATCH 0/3] net/sched: Load modules via alias

["Michal Koutný" <mkoutny@suse.com>]

These modules may be loaded lazily without user's awareness and
control. Add respective aliases to modules and request them under these
aliases so that modprobe's blacklisting mechanism (through aliases)
works for them. (The same pattern exists e.g. for filesystem
modules.)

Original module names remain unchanged.

Patches were generated with the help of Coccinelle scripts like:

+char module_alias = K;
