Subject: [PATCH 3/7] sky2: simplify list element error
Date: Tue, 18 Aug 2009 18:17:07 -0700	[thread overview]
Message-ID: <20090819011738.760531366@vyatta.com> (raw)
In-Reply-To: 20090819011704.685802801@vyatta.com

[-- Attachment #1: sky2-le-error.patch --]
[-- Type: text/plain, Size: 2017 bytes --]

The code for list element error (which should only happen on hardware
errors) should be cleaner and safer. Gets rid of unused ring_size
argument, which makes next patch easier.
