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.

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

In ocfs2, the inode block search looks for the "emptiest" inode group to allocate from. So if an inode alloc file has many equally (or almost equally) empty groups, new inodes will tend to get spread out amongst them, which in turn can put them all over the disk. This is undesirable because directory operations on conceptually "nearby" inodes force a large number of seeks. So

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 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
