    Subject[PATCH 0/4] linux-2.6-block: deactivating pagecache for benchmarks
    Hi Jens!

    For doing benchmarks on the I/O-Schedulers, I thought it would be very
    useful to disable the pagecache.

    I didn't want to make it so complicated so I just mark pages as
    not-uptodate, so they have to be read again. Another reason was, that I
    wanted to keep the conditions as near to reality as possible.

    Further I thought it would be useful, if you could turn the pagecache on
    and off without rebooting the system.

    I implemented a proc-fs entry "/proc/benchmark/pagecache" for this.

    Probably this patch can be useful for anyone else, who wants to do some
    benchmarks on block-layer stuff.
    And if not, I would appreciate if you could have a look on it.
