I have addressed the (small) review comments from Christoph, and rebased it on top of for-4.10/block, since that now has the flag unification and fs side cleanups as well. This impacted the prep patches, and the wbt code. I'd really like to get this merged for 4.10. It's block specific at this point, and defaults to just being enabled for blk-mq managed devices. Let me know if there are any objections. -- To unsubscribe from this list: send the line "unsubscribe linux-block" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
