That and the fact that on NAND flash you have to write full pages at a time -- that's 512 bytes, 2KiB or 4KiB depending on the type of chip. So we really do want to buffer it where we can. We don't want to write a 2KiB page for every line of printk output. -- David Woodhouse Open Source Technology Centre David.Woodhouse@...el.com Intel Corporation -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
