And is the allocator needed in this case? If yes, I beg you not to drop it, because we use one NPE for this purpose, and if we are going to adopt this driver instead of the intel's one, you will receive a patch adding DMA functionality very soon. ;) - 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/
