[pve-devel] [PATCH] rbd : free_image : retry if rbd has watchers

[Alexandre DERUMIER]

also this one:
http://lists.gnu.org/archive/html/qemu-devel/2014-10/msg02538.html
"block/mirror: Improve progress report"

"Instead of taking the total length of the block device as the block
job's length, use the number of dirty sectors. The progress is now the
number of sectors mirrored to the target block device. Note that this
may result in the job's length increasing during operation, which is
however in fact desirable."


I think we need to test qemu 2.2 block mirror,
because we are checking : 
if ($stat->{len} == $stat->{offset}) {



and they are some changes:
+        /* s->common.offset contains the number of bytes already processed so
+         * far, cnt is the number of dirty sectors remaining and
+         * s->sectors_in_flight is the number of sectors currently being
+         * processed; together those are the current total operation length */
+        s->common.len = s->common.offset +
+                        (cnt + s->sectors_in_flight) * BDRV_SECTOR_SIZE;
