The cls_,sch_,act_ modules may be loaded lazily during network
configuration but without user's awareness and control.
Switch the lazy loading from canonical module names to a module alias.
This allows finer control over lazy loading, the precedent from
commit 7f78e03513 ("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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
