...he filesystem and one for the external journal device. - Accelerate an O(N^2) algorithm in log_do_checkpoint(). - Accelerate an O(N^2) algorithm in journal_commit_transaction(). - Rate-limit some error messages which can come out when we're hopelessly out of memory. - Honour __GFP_WAIT in journal_try_to_free_buffers(). The fs is supposed to perform synchronous writeout on the second pass of page_launder() and we weren't doing that - we were starting all IO async. The net effect of this change is to decrease throughout with dbench by 10-20%, but system CPU time goes from 60% to 30%. It's the...

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
