Hi, I split the previous support security EA patch into four patches for review. Them besed on joel's xattr-28 branch and tao's patch "Merge xattr set transaction". 1: move new_inode out of the transaction. 2: add ocfs2_xattr_set_handle. 3: add security xattr APIs 4: add init_security in mknod. Best regards, tiger

.... ocfs2: Free block to the right block group. ocfs2: Set ac_last_group properly with discontig group. ocfs2: enable discontig block group support. ocfs2: make ocfs2_adjust_resv_from_alloc simple. ocfs2/trivial: Code cleanup for allocation reservation. ocfs2: Make ocfs2_extend_trans() really extend. ocfs2: Reset xattr value size after xa_cleanup_value_truncate(). ocfs2: Don't retry xattr set in case value extension fails. Tristan Ye (4): Ocfs2: Optimize ocfs2 truncate to use ocfs2_remove_btree_range() instead. Ocfs2: Fix hole punching to correctly...

ocfs2 currently uses the Journaled Block Device (JBD) for its journaling. This is a very stable and tested codebase. However, JBD is limited by architecture to 32bit block numbers. This means an ocfs2 filesystem is limited to 2^32 blocks. With a 4K blocksize, that's 16TB. People want larger volumes. Fortunately, there is now JBD2. JBD2 adds 64bit block number support and some other

Hi Mark/Joel, These are 2 bug fix for b-tree. Please review. I have sent out the first one last week, but it was based on cacheme. So resend it. Now it bases on joel's fixes branch. The second one is another b-tree rotation bug. I guess the reason why we never meet with it is that no one has ever used b-tree like reflink before. ;) Regards, Tao

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, 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 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, 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

I'm running a bit late with the e-mail this time around, but I think that's ok since there really isn't any major new features here - the bulk of the Ocfs2 update is bug fixes, or cleanups. The same goes for configfs. The only two things that could be described as features would be: - Sunil has updated Ocfs2 to provide even more live cluster locking information via debugfs. - Joel

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
