NAME
       __request_module - try to load a kernel module

SYNOPSIS
       int __request_module(bool wait, const char * fmt, ...);

ARGUMENTS
       wait
	   wait (or not) for the operation to complete

       fmt
	   printf style format string for the name of the module @...: arguments as specified in the format string

       ...
	   variable arguments

DESCRIPTION
       Load a module using the user mode module loader. The function returns zero on success or a negative errno code on failure. Note that a
       successful module load does not mean the module did not then unload and exit on an error of its own. Callers must check that the service
       they requested is now available not blindly invoke it.

       If module auto-loading support is disabled then this function becomes a no-operation.
