loading modules

[blesson paul]

Hi all
		I am a newbie  to Kernel world. When I looked into the file system files, 
I found that the initialization function ( where the file system is 
registered) is “init_filesystem”  where filesystem can be coda, vfat etc. As 
far as know, the initialization function is
	int init_module(void)
		Then how kernel takes different initialization functions. I want to know 
whether my know how is wrong or not

Thanking in advance
regards
Blesson Paul

you have something like (function parameters supressed for simplifcation):

/* Kernel calls this in your module */
init_module()
{

do_something();
init_filesystem(...);

return whatever;
}


So the entry point for every kind of module, including filesystem 
modules, is init_module(), you don't implement init_filesystem in the 
module, you call it to let the kernel know you want to register a 
filesystem.
