From 7db6f5fb65a82af03229eef104dc9899c5eecf33 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Sun, 27 Jun 2010 01:02:33 +0000 Subject: vsprintf: Recursive vsnprintf: Add "%pV", struct va_format Add the ability to print a format and va_list from a structure pointer Allows __dev_printk to be implemented as a single printk while minimizing string space duplication. %pV should not be used without some mechanism to verify the format and argument use ala __attribute__(format (printf(...))).

Mattock" Date: Thu, 1 Jul 2010 14:28:27 -0700 Subject: fix #warning about using kernel headers in userpsace Move the preprocessor #warning message: warning: #warning Attempt to use kernel headers from user space, see http://kernelnewbies.org/KernelHeaders from kernel.h to types.h. And also fixe the #warning message due to the preprocessor not being able to read the web address due to it thinking it was the start of a comment. also remove the extra #ifndef _KERNEL_ since it's already there.
