    Whoops! The create test is exactly the case my index patch
    accelerates, trying it is highly recommended:

    To apply:

    cd source/tree
    zcat ext2-dir-patch-S4.gz | patch -p1
    cat dx.pcache-2.4.4 | patch -p0

    Or for the all-in-page-cache version (needs Al Viro's patch, see the
    READ.ME at

    The testme version is easier to apply but the pcache version is more
    like what the final form will be (waiting for Al's patch to get into
    Linus's tree so I can de-fork this).
