See http://www.infradead.org/rpr.html Precedence: bulk List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Just to despit my 2 cents again: I think the way this is specified in the virtio spec is actively harmful and we should not suport it in Linux. If others override me we at least need to require a detailed documentation of these fields as the virto spec does not provide it. Please also do not add pointless over 80 character lines, and follow the one value per sysfs file rule.
