    Me? Radix tree based approach? That approach is in the kernel. Do not
    create a solution where there is no problem. If we do not want to
    support large blocksizes then lets be honest and say so instead of
    redefining what a block is. The current approach is fine if one is
    satisfied with scatter gather and the VM overhead coming with handling
    these pages. I fail to see what any of what you are proposing would add to
    that.

    Lets be clear here: A bigger page cache size if its just one is not
    useful. 4k page size is a good size for many files on the system and
    chaning it would break the binary format.. I just do not want it to be the
    only one because different usage scenarios may require differnet page
    sizes for optimal application performance.
