1) What makes you think this is broken, and not just a case of the
attribute cache timing out and/or the directory changing?
2) Can you produce a testcase that proves brokenness?
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.
