Subject: [PATCH 1/6] asm-generic/atomic.h: simplify inc/dec test helpers
Date: Fri, 17 Jun 2011 17:53:29 -0400	[thread overview]
Message-ID: <1308347614-402-2-git-send-email-vapier@gentoo.org> (raw)
In-Reply-To: <1308347614-402-1-git-send-email-vapier@gentoo.org>

We already declared inc/dec helpers, so we don't need to call the
atomic_{add,sub}_return funcs directly.
