Subject: [PATCH] qemu: capabilities: Add QEMU_CAPS_BLOCKDEV_REOPEN
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This capability will be asserted once qemu stabilizes 'blockdev-reopen'.
For now we just add the capability so that we can introduce some code
that will use the reopening call. This will show our willingness to
adopt use of reopen and help qemu developers stabilize it.
