Date: Fri, 9 May 2014 14:52:23 +0200 From: Michal Marek <mmarek@...e.cz> To: linux-kbuild@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Sam Ravnborg <sam@...nborg.org> Subject: [PATCH v2 4/5] kbuild: Use relative path when building in the source tree When not using O=, $(srctree) refers to the same directory as $(objtree), so we can set it to '.' as well. This makes the default include path more compact and results in more readable messages from the compiler. The only case where we need the absolute path is when creating the 'source' symlink in /lib/modules.
