[Qemu-block] [PATCH v5 0/5] minor qcow2 compression improvements

[Eric Blake]

Another attempt at this series; v4 was over a month ago:
https://lists.gnu.org/archive/html/qemu-devel/2018-02/msg06780.html

Since then: add R-b, and another round of wording tweaks [Berto, Max],
emphasizing that refcount table is not the limiting factor and that
other limits like ext4 are more likely to hit first
