| |
Hi,
I'd like to see LOG_BUF_LEN from kernel/printk.c moved to a header file so that some non-kernel (kernel-mode) tools can know the value being used (tools like kmsgdump or lkcd etc.).
This patch moves LOG_BUF_LEN to include/linux/kernel.h . Or it could go to a separate (new) header file...
Comments?
Thanks, -- ~Randy
