[RFC] Expose request_module via syscall

["Thomas Weißschuh" <thomas@t-8ch.de>]

Hi,

I would like to propose a new syscall that exposes the functionality of
request_module() to userspace.

Propsed signature: request_module(char *module_name, char **args, int flags);
Where args and flags have to be NULL and 0 for the time being.

Rationale:

We are using nested, privileged containers which are loading kernel modules.
Currently we have to always pass around the contents of /lib/modules from the
root namespace which contains the modules.
(Also the containers need to have userspace components for moduleloading
installed)

The syscall would remove the need for this bookkeeping work.

If this has a chance of getting accepted I would be happy to provide an
implementation.

Thanks,
Thomas
