...the metadata I/O API. The remaining 34 patches slowly but surely move alloc.c to the new API. Our btree code is heavily invested in the idea that all btrees are rooted, somehow, at an inode. Since we want to root a btree at a non-inode, we need to fix that. The good news, of course, is that the ocfs2_extent_tree abstraction is already there to rescue us. We attach the ocfs2_caching_info to a particular ocfs2_extent_tree, and we can then send that ocfs2_extent_tree down through the btree code. At the end of this series, the generic btree code doesn't reference struct inode at all. There are a lot of...

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 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, 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).

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 patch was created against a 1.4 tree. However, it applies cleanly to mainline too. The patch has been lightly tested. I am running fill_verify_holes on a non sparse volume currently. Please review. Sunil

Hi Mark/Joel, This is the v2 of bug fix for ocfs2_add_branch. Modification from V1 to V2: 1. Create a patch which return EROFS instead of BUG in ocfs2_insert_at_leaf. 2. Use ocfs2_adjust_rightmost_records to change the root and extent blocks in the rightmost path. Regards, Tao

For nfs exporting, ocfs2_get_dentry() returns the dentry for fh. ocfs2_get_dentry() may read from disk(when inode not in memory) without any cross cluster lock. this leads to load a stale inode. this patch fixes above problem. solution is that in case of inode is not in memory, we get the cluster lock(PR) of alloc inode where the inode in question is allocated from(this causes node on which

Hi, This is the second batch of Ocfs2 patches intended for the merge window. The 1st batch were sent out previously: http://lkml.org/lkml/2008/12/19/280 The bulk of this set is comprised of Jan Kara's patches to add quota support to Ocfs2. Many of the quota patches are to generic code, which I carried to make merging of the Ocfs2 support easier. All of the non-ocfs2 patches should have
