From bb40ebce2cb0bd4bf37968074d43d5a864fb6dee Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Tue, 24 Mar 2020 12:42:31 -0500 Subject: qcow2: List autoclear bit names in header The feature table is supposed to advertise the name of all feature bits that we support; however, we forgot to update the table for autoclear bits. While at it, move the table to read-only memory in code, and tweak the qcow2 spec to name the second autoclear bit. Update iotests that are affected by the longer header length.
