Message-ID: <20100201185640.GF11045@lst.de>
Date: Mon, 1 Feb 2010 19:56:40 +0100
From: Christoph Hellwig <hch@....de>
To: akpm@...ux-foundation.org, linux-kernel@...r.kernel.org,
linux-arch@...r.kernel.org
Cc: ralf@...ux-mips.org, benh@...nel.crashing.org, lethal@...ux-sh.org,

Subject: [PATCH 6/6] generic sys_olduname
Add generic implementations of the old and really old uname system calls.
Note that sh only implements sys_olduname but not sys_oldolduname, but
I'm not going to bother with another ifdef for that special case.
m32r implemented an old uname but never wired it up, so kill it, too.
