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.
