2.6.16 sock_init() problem
[root@localhost net]# uname -a
Linux localhost.localdomain 2.6.16.1 #3 SMP Sun Sep 17 20:38:49 CST 2006 i686 i686 i386 GNU/Linux
/linux/init.h:
#define __define_initcall(level,fn) \
static initcall_t __initcall_##fn __attribute_used__ \
__attribute__((__section__(".initcall" level ".init"))) = fn
#define core_initcall(fn) __define_initcall("1",fn)
typedef int (*initcall_t)(void);
i don't understand the macrodefinition,why "=fn"
that's my question,thanks a lot!
