Hello,

Just quick busdma question...

I'm currently upgrading a custom device driver to use 
bus_dmamap_load_uio rather than uiomove. Everything works fine, but 
calls to "write" fail unless I set uio->uio_resid to 0 by hand (as I'm 
not using uiomove anymore).

Am I supposed to set uio_resid by hand when using bus_dmamap_load_uio, 
or is there a better way to signal that all the data in uio was used?
