[Qemu-devel] [PATCH v2 2/2] qcow2: COMPRESSED on count_contiguous_cluste


From: Max Reitz
Subject: [Qemu-devel] [PATCH v2 2/2] qcow2: COMPRESSED on count_contiguous_clusters
Date: Fri, 27 Sep 2013 12:14:16 +0200

Compressed clusters can never be contiguous, therefore the corresponding
flag does not need to be given explicitly to count_contiguous_clusters.
