How can a loadable kernel module remove itself?

How can a loadable kernel module remove itself?

[Alan Stern]

Say I've got a kernel module that decides its job is done, and it wants to 
unload itself automatically.  Is there any way to do that?  Basically I'm 
looking for the opposite of the request_module() function, except that 
I've already got a pointer to the module in question, i.e., THIS_MODULE.

Thanks,

Alan Stern

If the module's runtime is *really* limited (eg. I oftenly use very
small modules to printk() me some bytes from some in-kernel data
structures), then just do what you need to do in the function
"registered" with module_init() and return with != 0...
