    Hi,

    FiSC found that at link operation and unlink operation on a NFS partion on
    top of JFS are not sync'ed. These warnings show up in JFS but not in
    ext2, ext3, so I suspect it's a potential JFS problem.

    cat /etc/exports shows:
    /mnt/sbd0-export localhost(rw,sync,no_subtree_check)
    /mnt/sbd1-export localhost(rw,sync,no_subtree_check)

    test cases can be found at:

    http://fisc.stanford.edu/bug17/crash.c

    Thanks,
    -Junfeng
