Still didn't got a time to test with vanilla kernel. But got some details.
It's works as expected with sec=sys. With sec=krb5 I see this effect.
Unfortunately kernel crashes as soon as I try to re-run tests. It simply
freezes with no stack traces....

This 2.6.37 + pnfs-all-latests :

100% reproducible.
1) What makes you think this is broken, and not just a case of the
attribute cache timing out and/or the directory changing?
The directory does not changed. I issue 'ls -l' and with wireshak can
see READDIR requests
followed by GETATTR. looks like cache is ignored or too small.
2) Can you produce a testcase that proves brokenness?
I will try to come up with something.
3) Can you reproduce on a non-pnfs-all-latests kernel?
Readdir shouldn't be affected by the stuff in Benny's tree, but I'm
always wary of tests on out-of-mainline trees.
NP. with vanilla 2.6.37 ?
