Subject: [Ocfs2-devel] [PATCH] ocfs2: correctly update i_used in ocfs2_free_local_alloc_bits
Date: Mon, 25 Nov 2013 14:11:00 +0800 [thread overview]
Message-ID: <5292E9F4.9090808@huawei.com> (raw)
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.
