NFS async writes working in 2.4.7 but not 2.4.20

    Hello,

    I have a RH 7.2 workstation that is nfs mounting some directories. It works fine
    under kernel 2.4.7. However, If I switch to kernel 2.4.20-xfs (the stock 2.4.20,
    with Sun's XFS patch), then my NFS writes become very slow -- approx 10 seconds
    to copy 1MB to the nfs file system. Reads are unaffected.

    I'm assuming this has something to do with the nfs sync/async options. I've
    tried putting the async option in /etc/fstab to no avail.

    While I'm sure I can dig through the kernel myself and figure out what is going
    wrong, I was hoping somebody just "knew" what the problem was....

    Thanks,
    Scott

    FYI, keep in mind that you can set async/sync at both the server
    (e.g. /etc/exports) *and* client side (e.g. /etc/fstab) of things.
