Subject: [PATCH v2 selftests 2/6] selftests: memfd: Stop unnecessary rebuilds
Date: Mon, 2 Nov 2015 12:21:57 +0000 [thread overview]
Message-ID: <20151102122157.GC17015@decadent.org.uk> (raw)
In-Reply-To: <20151102122048.GA17015-/+tVBieCtBitmTQ+vhA3Yw@public.gmane.org>

Instead of explicitly running the compiler, add dependencies and take
advantage of implicit rules to build only as necessary.
