[Qemu-devel] [RFC PATCH 03/10] block: add a function to clear incoming live migration |
Date: |
Tue, 6 Mar 2012 18:32:22 +0100 |
This function is to be called to inform the block layer that an
incoming live migration has been canceled or has just finished.
It will also clear all BDRV_O_INCOMING flags.
