[PATCH] Delete redundant init_module and cleanup_module prototypes.

Rusty Russell (rusty@rustcorp.com.au)
Tue, 24 Jun 2003 12:13:27 +1000


Linus, please apply.

A few places pre-declare "int module_init(void);" and "void
module_cleanup(void);". Other than being obsolete, this is
unneccessary (it's in init.h anyway).

There are still about 100 places which still use the
obsolete-since-2.2 "a function named module_init() magically gets
called": this change frees us up implement that via a macro.
