[PATCH 0/3] printk: add macros to simplify handling struct va_format

Posted by Andrzej Hajda 5 days, 10 hours ago

This patchset contains patch abstracting out most common bits of va_format uses
into small macro. The macro works as a forwarder of variadic args to va_format
call.
Rough estimates based on dirty cocci script suggests about 180-230 users
could be converted, allowing to remove about 1100-1300 lines of code.
Of course, I do not plan to do it in mass. I just provide two patches to
show the usage and potential.
