Ext3 users - Sep 2001 - ext3-2.4-0.9.10

An ext3 patch against linux 2.4.10 is at

	http://www.uow.edu.au/~andrewm/linux/ext3/

This patch is *lightly tested* - ie, it boots and does stuff.
The changes to ext3 are small, but the kernel which it patches
has recently changed a lot.  If you're cautious, please wait
a couple of days.

The patch retains the buffer-tracing code.  This will soon be
broken out into a separate patch to make ext3 suitable for
submission for the mainstream kernel.

Changelog:

- Fix an oops which could occur at unmount time due to non-empty
  orphan list.  This could be triggered by an earlier error during a
  truncate.

- Merge Ted's directory scan speedup heuristic.

- Remove the abort_write() address_space_operation by ensuring that
  all prepare_write() callers always call commit_write().

- A number of changes to suit the new 2.4.10 VM and buffer-layer design.
