[Devel] [PATCH VZ10 v2 0/7] dm-qcow: lseek improvements

[Vasileios Almpanis]

> This patchset is mostly about improving dm-qcow2 lseek speed. L2 md
> pages can now be scanned in batch with simple for() instead of heavy
> parse_metadata(). Seek qios for backing images are now called with
> a range bigger than 1 cluster if possible.
> Also fix a few clamping bugs and use correct comparison for seek
> modes.
LGTM
