how to expand linux kernel macro in kernel source code/kernel module(outside)
Recently I was learning doubly linked list in kernel, there are many macro in linux/fs.h, like list_add, list_del,list_for_each,list_entry, container_of. I know we can use "gcc -E" to expand the macro, but how do we expand the macro in kernel source code / kernel module? - mudongliang

You may want to try following. That will expand all the macros in kernel/cpu.c file. # make kernel/cpu.i You may try with your required files. Vishal On Tue, Oct 6, 2015 at 9:17 PM, Manavendra Nath Manav <mnm.kernel@gmail.com> wrote:
