From ceabef7dd71720aef58bd182943352c9c307a3de Mon Sep 17 00:00:00 2001 From: Orson Zhai Date: Sun, 7 Jun 2020 21:40:14 -0700 Subject: dynamic_debug: add an option to enable dynamic debug for modules only Instead of enabling dynamic debug globally with CONFIG_DYNAMIC_DEBUG, CONFIG_DYNAMIC_DEBUG_CORE will only enable core function of dynamic debug. With the DYNAMIC_DEBUG_MODULE defined for any modules, dynamic debug will be tied to them. This is useful for people who only want to enable dynamic debug for kernel modules without worrying about kernel image size and memory consumption is increasing too much.
