Hi, For EAs data structure in inode/block are little different from them in bucket. These two patches try to make them same for the most part. The first patch set xh_free_start and xh_name_value_len when EAs in inode/block. xh_free_start is useful to keep the minimum offset of the xattr name/value. But xh_name_value_len is not very useful because we don't have "hole" when EAs in

When the extended attribute namespace 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

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, 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

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
