+C<guestfs_btrfs_subvolume_show> would sometimes crash when parsing the
+snapshots of a Btrfs subvolume.  Furthermore, in any API that returned
+a device name associated with a Btrfs volume, the device name might
+not be translated correctly resulting in the wrong device name being

+In C<guestfs_disk_create>, when creating raw block devices, check for

+delayed I/O errors (Susant Sahani).

+In several LVM-related APIs, it was possible for an internal failure
+to happen for logical volumes which are incomplete (eg. missing a
+physical volume).  This was fixed by skipping these LVs (Arye
+Yurkovsky).
