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

    http://nl.linux.org/~phillips/htree/dx.testme-2.4.3-3

    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 http://nl.linux.org/~phillips/htree/):

    http://nl.linux.org/~phillips/htree/dx.pcache-2.4.4-4

    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).
