Ok, so the flush_dcache_page() interface looses this; the original placement of the flush_page_to_ram() ensured that data written by device drivers was visible to user space.
That's possible, but see my response to Roman's posting for how this can be easily fixed using current interfaces yet retaining identical or even potentially better performance. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
