=== Series dependencies ===
This series depends on v7 of Stefan's series
"qemu-img: add measure sub-command"
(http://lists.nongnu.org/archive/html/qemu-devel/2017-06/msg03035.html).
=== Actual cover letter ===
This series adds preallocation to bdrv_truncate() and subsequently
qemu-img resize. This is implemented for qcow2 and raw only, just like
preallocation for newly created images is. There is no runtime interface
for this new parameter (yet).
v4:
- Patch 4:
- Note bug fix in commit message [Eric]
- "...may result in *slightly* more data being allocated..." [Eric]
- Patch 11:
- Drop the "image may now occupy more space than necessary" note --
that's always the case when preallocation failed, and I don't really
want to mention it everywhere
- Flush metadata after preallocation [Stefan]
git-backport-diff against v3:
Key:
[----] : patches are identical
[####] : number of functional differences between upstream/downstream patch
[down] : patch is downstream-only
The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively
