[Qemu-devel] [PATCH 0/5] qcow2 fixes


From: Kevin Wolf
Subject: [Qemu-devel] [PATCH 0/5] qcow2 fixes
Date: Fri, 28 May 2010 13:22:48 +0200

Another series of fixes for bugs that were found using blkdebug. The last two
of them are presumably relevant even outside error paths and can cause
corruption. They should be applied to stable-0.12, too.

Kevin Wolf (5):
  qcow2: Allow qcow2_get_cluster_offset to return errors
  qcow2: Change l2_load to return 0/-errno
  qcow2: Return right error code in write_refcount_block_entries
  qcow2: Fix corruption after refblock allocation
  qcow2: Fix corruption after error in update_refcount
