Implemented the suggestions. Also, moved the ocfs2_orphan_scan_init() to the end of ocfs2_fill_super() instead of calling it earlier in ocfs2_initialize_super(). Sunil

Hi Joel/Srini, Here are 2 patches for orphan lock in local mode. patch 1: In local mode, we don't need lvb, so don't init it. patch 2: In local mode, orphan lock and unlock don't need to go to dlm part. Regards, Tao

Resending after implementing review comments.

Hi, I'm resending this patch series. It's rediffed against linux-next branch of Joel's git tree. The first four patches are obvious fixes of deadlocks in quota code and should go in as soon as possible. The other three patches implement lockdep support for OCFS2 cluster locks. So you can have a look whether the code make sence to you and possibly merge them. They should be NOP when

The following series of patches comprises the bulk of our outstanding changes for Ocfs2. Aside from the usual set of cleanups and fixes that were inappropriate for 2.6.25, there are a few highlights: The '/sys/o2cb' directory has been moved to '/sys/fs/o2cb'. The new location meshes better with modern sysfs layout. A symbolic link has been placed in the old location so as to

Hi, here comes the next version of OCFS2 lockdep support. I've dropped patches with fixes from the series since they were already merged. As Joel suggested, I've simplified the main patch a bit so that we don't have ifdefs around lock declarations and there are also a few other minor improvements. Honza

Hi, the first four patches in this series fix locking problems in OCFS2 quota code (three of them can lead to potential deadlocks). The fifth patch reorders ip_alloc_sem for directories to be acquired before localalloc locks. Mark would you please merge these? The last two patches implement lockdep annotations for OCFS2 cluster locks. We annotate all the cluster locks except for special ones

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, 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

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
