    SubjectRe: nfsv2 ref leak in 2.6.24?
    Trond, good news.  I was able to narrow down the problem to purely the
    client-side, probably dcache/readdir related, and I have a shell script that
    deterministically triggers the problem each time for me (this is a FC6 image
    under Vmware 6.0.1). Here's a short shell script which reliably triggers
    the "lost files" problem -- I create a file via nfs2 on the client side, and
    sometimes it doesn't show up in readdir, but it is there if you stat it
    directly.

    BTW, since this is a client-side bug, I also tried your last set of posted
    client patches for Linus, but it didn't help.

    Happy hunting. :-)

    Erez.
