Ok. Your config should have CONFIG_DYNAMIC_DEBUG defined,
and my config does not have that defined.
we have linux/kernel.h
linux/printk.h
linux/dynamic_debug.h
dynamic_debug.h will include linux/string.h when CONFIG_DYNAMIC_DEBUG
is not defined.
Hi, Andrew,
How to fix this inconsistency caused by dynamic_debug.h
1. let linux/kernel.h include string.h directly
2. or let dynamic_debug include string.h always
3. let printk.h include string.h.
