[Qemu-devel] [PATCH v4 9/9] qapi: Add transaction support to dirty-bitmap-{add, disable}

2014-03-27 Thread Fam Zheng
This adds dirty-bitmap-add and dirty-bitmap-disable to transactions. With this, user can stop a dirty bitmap, start backup of it, and start another dirty bitmap atomically, so that the dirty bitmap is tracked incrementally and we don't miss any write. Signed-off-by: Fam Zheng --- blockdev.c
