[Qemu-devel] [PATCH for 3.1 v3 0/3] minor qcow2 compression improvements

[Eric Blake]

As the added iotests shows, we have a (corner case) data corruption
that is user triggerable, therefore, this is still appropriate for
inclusion in 3.1.

v6 was here:
https://lists.gnu.org/archive/html/qemu-devel/2018-06/msg08497.html

since then:
- don't reduce constraints on reftable [Kevin]
- rebase to recent iotests changes
- drop patches that might conflict with Vladimir's work now on Kevin's
block-next branch

001/3:[0042] [FC] 'qcow2: Document some maximum size constraints'
002/3:[0003] [FC] 'qcow2: Don't allow overflow during cluster allocation'
003/3:[0003] [FC] 'iotests: Add new test 220 for max compressed cluster offset'

  qcow2: Document some maximum size constraints
  qcow2: Don't allow overflow during cluster allocation
  iotests: Add new test 220 for max compressed cluster offset
