Oh, and let me re-iterate: the purpose of the patch I supplied to Texas was to solve _their_ specific problem, which is to get the DSP bridge driver working. It is *not* a generic interface for kernel drivers to use. That's why I ignored your comment about kernel interfaces for flusing userspace buffers. It's just not relevant to the problem at hand. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
