Switch the lazy loading from canonical module names to a module alias. This allows finer control over lazy loading, the precedent from commit 7f78e0351394 ("fs: Limit sys_mount to only request filesystem modules.") explains it already: Using aliases means user space can control the policy of which filesystem^W net/sched modules are auto-loaded by editing /etc/modprobe.d/*.conf with blacklist and alias directives. Allowing simple, safe, well understood work-arounds to known problematic software. By default, nothing changes. However, if a specific module is blacklisted (its canonical name), it won't be modprobe'd when requested under its alias (i.e. kernel auto-loading). It would appear as if the given module was unknown. The module can still be loaded under its canonical name, which is an explicit (privileged) user action.

They have aliases to make autoloading work for any of the provided functionalities. Since the autoloading was changed to uniformly request any functionality under its alias, the non-systemic aliases can be removed now (i.e. assuming the alias were only used to ensure autoloading).
