    SubjectRe: [RFC PATCH 0/6] Convert all tasklets to workqueues
    A couple of days ago I said:

    > The cafe_ccic (OLPC) camera driver uses a tasklet to move frames out of

    I've done that testing - I have an OLPC B3 unit running V2 of the
    tasklet->workqueue patch, and all seems well. 30 FPS to the display and
    no dropped frames. The tasklets/0 process is running 3-5% CPU, in case
    that's interesting. For whatever reason, I see about 3% *more* idle
    time when running just mplayer than I did without the patch.

    Consider my minor qualms withdrawn, there doesn't seem to be any trouble
    in this area.
