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.

Two patches follow this message. One fixes the default implementation of SEEK_HOLE/DATA. This patch applies atop Josef's last posted patch. The second patch implements the same on ocfs2. The test tool for the same is available here. http://oss.oracle.com/~smushran/seek_data/seek_test.c It is improved since the last post. It runs cleanly on zfs, ocfs2 and ext3 (default behavior).

The old extent merging code down underneath "ocfs2_mark_extent_written()" can't merge extents between leaf blocks. This patch resolve this. So that a large unwritten extent which has been split up with a bunch of writes can be merged together once all unwritten regions have been written to. Modification from V1 to V2: 1. Add more comments for some functions which is more complicated

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 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

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 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
