Subject: [Qemu-block] [PATCH v10 03/16] qemu-io: Set "share-rw" flag together with read-only
Date: Thu, 19 Jan 2017 22:38:03 +0800

qemu-io is a low level tool to read or modify guest visible data, which
implies the user knows very well what is being done. Allowing reading
from a locked image is harmless in most cases, so do it.
