[Qemu-block] [PATCH 30/54] hw/block: Introduce share-rw qdev property |
|
Date: |
Tue, 21 Feb 2017 15:58:26 +0100 |
By default, don't allow another writer for block devices that are
attached to a guest device. For the cases where this setup is intended
(e.g. using a cluster filesystem on the disk), the new option can be
used to allow it.
This change affects only devices using DEFINE_BLOCK_PROPERTIES().
Devices directly using DEFINE_PROP_DRIVE() still accept writers
unconditionally.
