Hi Mark/Joel, This is the v2 of bug fix for ocfs2_add_branch. Modification from V1 to V2: 1. Create a patch which return EROFS instead of BUG in ocfs2_insert_at_leaf. 2. Use ocfs2_adjust_rightmost_records to change the root and extent blocks in the rightmost path. Regards, Tao

Hi, I have fixed the problems in version 1 patches. These two patches based on the latest main line kernel.

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

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

In ocfs2_value_metas_in_xattr_header, we should Use le16_to_cpu for ocfs2_extent_list.l_next_free_rec.

Can anyone tell me the history of CONFIG_EXT{2,3}_CHECK? There is code for a "check" option for mount if these options are enabled, but there's no way to enable them.

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

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
