From: Andrew Morton Date: Tue, 4 Mar 2008 22:28:40 +0000 (-0800) Subject: add noinline_for_stack X-Git-Tag: v2.6.25-rc4~70 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=735c4fb916e9f83a9350aeb2680d77d01ea75094;p=linux-2.6 add noinline_for_stack People are adding `noinline' in various places to prevent excess stack consumption due to gcc inlining. But once this is done, it is quite unobvious why the `noinline' is present in the code. We can comment each and every site, or we can use noinline_for_stack.
