Applying that patch to the SuSE kernel 2.6.8-24.14 seems to solve the
stale problem for me. Well, reading Tronds explanation, I guess it
does not really "solve" but maybe just hide the bug... If the client
does an equivlate of "cd `pwd`", then it will just recover from the
stale handle without the user recognizing it at all.

Anyway, with the normal SuSE 2.6.8-24.14 I get a stale "." whenever
I start firefox on the client and chdir to the firefox profile
directory. After 30 minutes the shell reliably has a stale directory.

With the patch applied and the client running the patched kernel,
(the server doesn't need to) there is no stale in this situation
after more than one day and that's all I need to make my users happy.

People in our department running server and client with 2.6.11 report
they still have massive problems with stale NFS handles, so it looks
like this patch just helped for a certain problem in 2.6.8...

cu,
Frank
