[Qemu-devel] [PATCH v2 04/16] qcow2: Keep unknown extra snapshot data

2019-08-19 Thread Max Reitz
The qcow2 specification says to ignore unknown extra data fields in snapshot table entries. Currently, we discard it whenever we update the image, which is a bit different from "ignore". This patch makes the qcow2 driver keep all unknown extra data fields when updating an image's snapshot table.
