SubjectRe: [Patch] fix a headers_check warning in include/linux/kernel.h
Date
Hi,

For the sake of having a patch ready. I actually did it yesterday but did not
send it then. Cc'ed to the authors of the relevant macros; __FUNCTION__ was
actually exported since ages, but I really do not see why the kernel exports
this macros...
