Re: [RFC PATCH 0/6] Convert all tasklets to workqueues

A couple of days ago I said:

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Consider my minor qualms withdrawn, there doesn't seem to be any trouble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

Thanks,
