IF core please just make them unisgned long, if they're ondisk you just sayd goodbye to binary compatiblity for BE and LE 64bit hosts.

Add online resize in tunefs.ocfs2 so that user can increase the volume when it is mounted.

The new code is dedicated to calculate free inodes number of all inode_allocs, then return the info to userpace in terms of an array. Specially, flag 'OCFS2_INFO_FL_NON_COHERENT', manipulated by '--cluster-coherent' from userspace, is now going to be involved. setting the flag on means no cluster coherency considered, usually, userspace tools choose none-coherency strategy by

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

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).
