From: kaigai@ak.jp.nec.com (Kaigai Kohei) X-Mailer: mnews [version 1.22PL1] 2000-02/15(Tue) Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1412 Lines: 35 [5/5] atomic_inc_return-linux-2.6.9-rc1.sparc64.patch This patch declares atomic_add_return() as an alias of __atomic_add(). atomic64_add_return(),atomic_sub_return() and atomic64_sub_return() are same. This patch has not been tested, since we don't have SPARC64 machine. I want to let this reviewed by SPARC64 specialists.
