Hi Bill,

linux-coda-5.2.3-linux2.2.9.tgz is identical to the code in the recent
official linux kernels (2.2.11+). It is the most up-to-date version, and
no changes are expected for 2.2.x, it seems to be reasonably rock solid.

For the 2.3.x series the patch that Chuck Lever posted to the linux-kernel
list in August and more testing are needed. But I've had some problems with
the 2.3 series on my laptop, so I haven't been able to run some Coda tests
without oopsing on something completely unrelated, I hope :)

The `df' output is something I added to find some leaks in the cache-usage
counters. It is reasonably useful, if you know what the various numbers

$ df /coda
Filesystem         1024-blocks  Used Available Capacity Mounted on
Coda                  100000     224    75589      0%   /coda
			^1	  ^2	  ^3	   ^4
1) total size of the venus cache.
2) size of non-reclaimable objects. Because of open for write or
   modified/logged while (write-)disconnected.
3) size used by cached objects.
4) 2 / 1 * 100%

$ df -i /coda
Filesystem           Inodes   IUsed   IFree  %IUsed Mounted on
Coda                    4166    1649    2517    40%  /coda
			 ^1	 ^2	 ^3	^4
1) total number of available fs objects (files/directories).
2) number of fs objects in use.
3) number of unused fsos.
4) 2 / 1 * 100%
