Linus et al,
Here are the ocfs2 updates for 2.6.35. There are two major
changes. Mark added allocation reservations to our node-local
allocators. This gets us much more contiguousness when many processes
are growing files in parallel. On the other end of contiguousness,
ocfs2 has had a major limitation since the beginning. When ocfs2 needs
new inodes, it has always grown its metadata allocators in contiguous
hunks. As you might expect, badly fragmented filesystems may be unable
to add new inodes even when there is plenty of unused space. Tao and I
have added discontiguous block groups to fix the problem.
There's also various small stuff. The shortlog is below. Please
pull.
Joel
