Subject[PATCH 4/4] kernel/param: Consolidate __{start,stop}___param[] in <linux/moduleparam.h>
Date
Consolidate the various external const and non-const declarations of
__start___param[] and __stop___param in <linux/moduleparam.h>.
This requires making a few struct kernel_param pointers in kernel/params.c
const.
