[Qemu-devel] [PATCH 03/14] qemu-io: Set "share-rw" flag together with read-only

[Fam Zheng <famz@redhat.com>]

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.
