[PATCH 0/3] ocfs2: Switch over to JBD2.
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

[PATCH 0/3] ocfs2: Inode Allocation Strategy Improvement.v2
Changelog from V1 to V2:
1. Modify some codes according to Mark's advice.
2. Attach some test statistics in the commit log of patch 3 and in
this e-mail also. See below.
Hi all,
In ocfs2, when we create a fresh file system and create inodes in it,
they are contiguous and good for readdir+stat. While if we delete all
the inodes and created again, the new inodes will get spread out and

[git patches] Ocfs2 updates for 2.6.30
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
