commit 7db6f5fb65a82af03229eef104dc9899c5eecf33
Author: Joe Perches <joe@...ches.com>
Date:   Sun Jun 27 01:02:33 2010 +0000

    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(...))).
