From ee1244a2e96288ba3c2f3a9a82b97f5617939d9f Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Tue, 28 Apr 2020 14:26:48 -0500 Subject: [PATCH] qcow2: Tweak comment about bitmaps vs. resize Our comment did not actually match the code. Rewrite the comment to be less sensitive to any future changes to qcow2-bitmap.c that might implement scenarios that we currently reject.
