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 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).

Hello ext3-developers, Just to summarize, I reported a kernel bug message with ext3 on S/390 in transaction.c. I was able to reproduce it with a ext3 on LVM and on MD. Tom Rini reported a similar problem on PPC. (both big endian). I have sent a backtrace and with jbd-debug set to 5 I was not able to reproduce the problem until now. On S/390 there are some more debug possibilities. I would

It would be nice to know how often we get checksum failures. Even better, how many of them we can fix with the single bit ecc. So, we add a statistics structure. The structure can be installed into debugfs wherever the user wants. For ocfs2, we'll put it in the superblock-specific debugfs directory and pass it down from our higher-level functions. The stats are only registered with

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.

Hi Stephen, I found a bug in JBD routine journal_create() in kernel 2.6, when I debug the OCFS v2 driver. mark_buffer_dirty() reports buffer_head is not uptodate. See following bug description. ------------------------------------------------------- OS: Linux Kernel 2.6.1 Plarform: IA32 Steps: 1. Build the ocfs v2 driver under kernel 2.6. 2. insert ocfs2.ko into kernel 2.6. 3. mkfs.ocfs2 -F

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 In ext3_get_parent(), quick string (struct qstr) can do the job, in place of declaring a dentry on stack. Following patch does this and saves few bytes on kernel stack.

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

I have ext3 0.0.6b + 2.2.19 and cannot get ext3 to compile as a module. If I try to modularize it, or turn in off completely, the kernel build fails. Is there an easy fix for this, or is there something that I am missing? Thanks. Peter

In __ocfs2_mark_extent_written, when we meet with the situation of c_split_covers_rec, the old solution just replace the extent record and forget to access and dirty the buffer_head. This will cause a problem when the unwritten extent is in an extent block. So access and dirty it.

Hi, These three patches fix the problems in the version two. And them base on the Tao's patches: ocfs2/xattr: xattr improvement The first patch fix some problem in xattr code. The second patch add security EA support. The third patch add ACL support. Best regards, tiger

ocfs2_queue_orphans() has an open coded readdir loop which can easily just use a directory accessor function.

Linus, et al, Here are the outstanding ocfs2 fixes we have for 2.6.30. The important ones are journal credit fixes for the new indexed directories. There's also MAINTAINERS update for my ocfs2 git tree. Please pull.

Hi all, this patch set are the backport of inode alloc improvement from mainline to ocfs2-1.4. the patches are almost the same excpet one thing: Joel has added JBD2 support to ocfs2, so he has added "max_blocks" to alloc_context and add a new function "ocfs2_reserve_clusters_with_limit". We don't have that in ocfs2-1.4. So there are some great difference in patch 2.

...grows to a b-tree, the leaf clusters are organized by means of 'buckets'. Each bucket is 4K in size, regardless of blocksize. Thus, a bucket may be made of more than one block. fs/ocfs2/xattr.c has a nice little abstraction to wrap this, struct ocfs2_xattr_bucket. It contains a list of buffer_heads representing these blocks, and there is even an API to fill it or initialize it. However, the majority of the code does not use this abstraction. Instead, it uses raw buffer_heads and jumps through other hoops. This has two consequences. First, it's harder to read. Second, it is less efficie...
