Subject: [Qemu-devel] [PATCH 0/2] qcow2: Respect new_block in alloc_refcount_block()
Date: Tue, 10 Feb 2015 15:02:30 -0500 [thread overview]
Message-ID: <1423598552-24301-1-git-send-email-mreitz@redhat.com> (raw)
Under certain circumstances, making the refcount table grow can result
in leaking clusters. The first patch fixes at least some of those
circumstances (maybe there are more, but these are the ones I am aware
of), and the second patch adds a test case.
