Subject: [Qemu-devel] [PATCH 38/38] docs: Fix missing carets in QED specification
Date: Fri, 17 Dec 2010 18:44:53 +0100 [thread overview]
Message-ID: <1292607893-13461-39-git-send-email-kwolf@redhat.com> (raw)
In-Reply-To: <1292607893-13461-1-git-send-email-kwolf@redhat.com>
From: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
For some reason the carets ('^') in the QED specification disappeared.
This patch puts them back.

Reads to an unallocated area of the image file access the backing file. If there is no backing file, then zeroes are produced. The backing file may be smaller than the image file and reads of unallocated areas beyond the end of the backing file produce zeroes.
