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). [View] http://oss.oracle.com/git/?p=tma/linux-2.6.git;a=shortlog;h=refcount [Pull] git://oss.oracle.com/git/tma/linux-2.6.git refcount 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, 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, 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
