Hi Pankaj,

I applied the first five patches and set minimum folio size for afs files to
8K (see attached patch) and ran some tests.

With simple tests, I can see in the trace log that it is definitely creating
8K folios where it would previously create 4K folios.

However, with 'xfstests -g quick', generic/075 generic/112 generic/393 fail
where they didn't previously.  I won't be able to look into this more till
Monday.

If you want to try using afs for yourself, install the kafs-client package
(available on Fedora and Debian), do 'systemctl start afs.mount' and then you
can, say, do:

	ls /afs/openafs.org/www/docs.openafs.org/

and browse the publicly accessible files under there.
