The fixes from the previous post are:
1) the in_flight_bitmap is now properly set and cleared [Stefan];
2) persistent dirty bitmap left out [Stefan];
3) reordered arguments in qmp-command.hx to follow patch order [Stefan];
4) tests/qemu-iotests/041.out is regenerated;
5) rebased for moved include files and for the discard series
Thanks!
Paolo
Paolo Bonzini (12):
host-utils: add ffsl
add hierarchical bitmap data type and test cases
block: implement dirty bitmap using HBitmap
block: make round_to_clusters public
mirror: perform COW if the cluster size is bigger than the granularity
block: return count of dirty sectors, not chunks
block: allow customizing the granularity of the dirty bitmap
mirror: allow customizing the granularity
mirror: switch mirror_iteration to AIO
mirror: add buf-size argument to drive-mirror
mirror: support more than one in-flight AIO operation
mirror: support arbitrarily-sized iterations
