Subject: [PATCH] qemu: capabilities: Add QEMU_CAPS_BLOCKDEV_REOPEN

This capability will be asserted once qemu stabilizes 'blockdev-reopen'.
|
|
|
fbe740 |
For now we just add the capability so that we can introduce some code
|
|
|
fbe740 |
that will use the reopening call. This will show our willingness to
|
|
|
fbe740 |
adopt use of reopen and help qemu developers stabilize it.
