OK thanks, I now have that, as
ocfs2-free-allocated-clusters-if-error-occurs-after-ocfs2_claim_clusters-fix.patch

Do we think that
ocfs2-free-allocated-clusters-if-error-occurs-after-ocfs2_claim_clusters.patch
and
ocfs2-free-allocated-clusters-if-error-occurs-after-ocfs2_claim_clusters-fix.patch
should now be merged upstream?
