I want to know where are these function point assigned by specified function ?
thanks!
As per include/asm-generic/vmlinux.lds.h and your arch's vmlinux.lds.S (I actually only looked at x86's), the __initcall_{start,end} variables are the start and end of the __initcall ELF section which contains all the sub-level sections.
Functions can be put into these sections when they are given to one of the *_initcall macros from include/linux/init.h.
I have configure kernel supporting rom filesystem ,and register it by module_init(init_romfs_fs) , but why the function : init_romfs_fs not be called from (*call)() ? thanks!
Regards, Tobi
