From 528f7663473e146fd1b435d73ca21b219451877c Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Fri, 25 Jun 2010 15:26:48 +0200 Subject: [PATCH] blockdev: Clean up how readonly persists across virtual media change Since commit cb4e5f8e, monitor command change makes the new media readonly iff the type hint is BDRV_TYPE_CDROM, i.e. the drive was created with media=cdrom. The intention is to avoid changing a block device's read-only-ness. However, BDRV_TYPE_CDROM is only a hint. It is currently sufficent for read-only. But it's not necessary, and it may not remain sufficient. Use bdrv_is_read_only() instead.
