similar to: [PATCH V2] ocfs2: need rollback when journal_access failed in ocfs2_orphan_add()

The following patches implement indexed directory support in Ocfs2, mostly according to the design doc I wrote up a while ago: http://oss.oracle.com/osswiki/OCFS2/DesignDocs/IndexedDirectories The patches have been rebased on top of 2.6.29-rc2. It should be trivial to put them into merge_window. Things are what I'd call complete now. I'd like to get these into the merge_window branch

Hi, The following patches comprise the bulk of Ocfs2 updates for the 2.6.30 merge window. Aside from larger, more involved fixes, we're adding the following features, which I will describe in the order their patches are mailed. Sunil's exported some more state to our debugfs files, and consolidated some other aspects of our debugfs infrastructure. This will further aid us in debugging

The following series of patches attempts to detach metadata I/O from struct inode. They are currently tied together pretty tightly. Metadata reads happen via the ocfs2_read_blocks() functions, writes via both jbd2 and ocfs2_write_blocks(). - Each inode has a cache of associated metadata blocks stored on its ip_metadata_cache member. The ocfs2_read/write_blocks() functions take a struct

In ctime updating of xattr, it use the wrong type of access for inode, so use ocfs2_journal_access_di instead.

Hi all, So I have finally finished the v1 of reflink for ocfs2. It has some bugs that I am still investigating, but the schema is almost there. So I'd like to send it out first for review. And Tristan and I will continue to work on the stability of the code. The general information for reflink, please see http://oss.oracle.com/osswiki/OCFS2/DesignDocs/Reflink. For the design doc, please

Hi all, Change from v1 to v2: bug fix and metadata/credits reservation improvement. The general information for reflink, please see http://oss.oracle.com/osswiki/OCFS2/DesignDocs/Reflink.

Hi all, So I have finally finished the v3 of reflink for ocfs2. The biggest change is that we support 64bit cluster offset now(Thank Mark and Joel for it).

Hi, I've been playing lately with lockdep annotations of OCFS2. I seem to have most of the false positives sorted out and currently I hit the report below. I've analyzed that ocfs2_extend_dir() does first lock local alloc inode in ocfs2_reserve_clusters() and then acquires ip_alloc_sem from the directory. The usual ordering e.g. in ocfs2_write_begin() is to first acquire ip_alloc_sem

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.

From: Zongxun Wang <wangzongxun at huawei.com> Even if using the same jbd2 handle, we cannot rollback a transaction. So once some error occurs after successfully allocating clusters, the allocated clusters will never be used and it means they are lost. For example, call ocfs2_claim_clusters successfully when expanding a file, but failed in ocfs2_insert_extent. So we need free the allocated
