0.9.7
-----

- Merge in a large batch of changes to allow ext3 to recover gracefully
  from fatal errors.  If the fs is set to remount-readonly on error, then
  we should still be able to unwind cleanly and unmount the filesystem.

- Performance: don't write superblocks synchronously.  This reduces a
  bottleneck in the VM.

  Load the ext3 module with the parameter "do_sync_supers=1" to restore
  the previous behaviour.

- Performance: don't force a new transaction every time we sync (should
  prevent the writes previously happening every 5 seconds, allowing laptop
  drives to spin down again.)

0.9.8
-----

- Fix an NFS oops when doing a local delete on an active, nfs-exported
  file.

- Add proper log levels to a lot of kernel warnings when mounting a bad
  filesystem or a fs with errors

- Make sure we set the error flag both in the journal and fs superblocks
  on error (unless we're doing panic-on-error)

0.9.9
-----

- Fix the buffer-already-revoked assertion failure by looking up an
  aliased buffercache buffer and clearing the revoke bits in there as
  well as in the journalled data buffer.

- Reorganise page truncation code so we don't take the address of
  block_flushpage().  This is to simplify merging with Andrea's
  O_DIRECT patch, which turns block_flushpage() into a macro.
