This patch is based on ocfs2-free-allocated-clusters-if-error-occurs- after-ocfs2_claim_clusters.patch. https://oss.oracle.com/pipermail/ocfs2-devel/2013-November/009461.html We should note down num of bits to be freed, so as to update i_used correspondingly after clearing those bits in bitmap.

I'm running a bit late with the e-mail this time around, but I think that's ok since there really isn't any major new features here - the bulk of the Ocfs2 update is bug fixes, or cleanups. The same goes for configfs. The only two things that could be described as features would be: - Sunil has updated Ocfs2 to provide even more live cluster locking information via debugfs. - Joel
