[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
