Subject: [PATCH] atomic_inc_return() for sparc64[5/5] (Re: atomic_inc_return)
Date: Fri, 10 Sep 2004 12:32:06 +0900 (JST) [thread overview]
Message-ID: <200409100332.i8A3W6YV007141@mailsv.bs1.fc.nec.co.jp> (raw)
In-Reply-To: Your message of "Thu, 9 Sep 2004 20:48:27 +0100 (BST)". <Pine.LNX.4.44.0409092005430.14004-100000@localhost.localdomain>
[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.
