diff from v2: ============ 1. Fix style issues. 2. Rework patch for fetching job info (save logic to use temporary variable when drop vm lock) 3. Update disk stats when block jobs are canceled. 4. Adress a few more corner cases. This patch series add disks stats to domain job info(stats) as well as to migration completed event in case nbd scheme is used. There is little nuisance with qcow2 disks (which is the main scenario I guess) tied to the way qemu reports stats for this type of disks. For example if we have 64G disk filled only to 1G then stats start from 63G and will grow up to 64G on completion. The same way disk stats will be reported by this patch. I guess the better way to express the situation is to say we have 64G 'total', and have 'processed' field grow from 0G to 1G, like in case of memory stats. [1] is the example of completed memory stats of empty guest domain, which show difference between processed and total. There can be a workaround like getting initial blockjob offset position as a zero but is is rather ugly and racy and like uses undocumented behaviour. Patches that were explicitly ACKed in previous review (up to style issues) marked with A.
