Subject: [Qemu-devel] [PATCH v2 0/2] qcow2: count_contiguous_clusters and compression
Date: Fri, 27 Sep 2013 12:14:14 +0200 [thread overview]
Message-ID: <1380276856-29777-1-git-send-email-mreitz@redhat.com> (raw)
Compressed clusters can never be contiguous and count_contiguous_clusters
will not even work correctly for them. Therefore, those cluster should
always be treated as non-contiguous.
This series makes count_contiguous_clusters always stop at compressed
clusters and removes the corresponding flag from its function calls.
v2:
- added patch 2 (following Kevin's proposal)
- patch 1 remains unmodified
Max Reitz (2):
qcow2: count_contiguous_clusters and compression
qcow2: COMPRESSED on count_contiguous_clusters
