Patch

From e2ae715d66bf4becfb85eb84b7150e23cf27df30 Mon Sep 17 00:00:00 2001
From: Kay Sievers <kay@vrfy.org>
Date: Fri, 15 Jun 2012 14:07:51 +0200
Subject: [PATCH] kmsg - kmsg_dump() use iterator to receive log buffer
 content

Provide an iterator to receive the log buffer content, and convert all
kmsg_dump() users to it.

The structured data in the kmsg buffer now contains binary data, which
should no longer be copied verbatim to the kmsg_dump() users.

The iterator should provide reliable access to the buffer data, and also
supports proper log line-aware chunking of data while iterating.
