[Qemu-devel] [PATCH] qcow2: Remove abort on free_clusters failure

[Kevin Wolf <kwolf@redhat.com>]

While it's true that during regular operation free_clusters failure would be a
bug, an I/O error can always happen. There's no need to kill the VM, the worst
thing that can happen (and it will) is that we leak some clusters.
