    The cafe_ccic (OLPC) camera driver uses a tasklet to move frames out of
    the DMA buffers in the streaming I/O path. With this change in place,
    I'd worry that the possibility of dropping frames would increase,
    especially considering that (1) this is running on OLPC hardware, and
    (2) there is typically a streaming video application running in user
    space.

    Obviously some testing is called for here. I will make an attempt to do
    that testing, but the next few weeks involve some insane travel which
    will make that hard. Stay tuned.

    Thanks,

    jon
