Please don't overload META even more, it's already overloaded with at least two meanings. We do in fact already have a REQ_FUA flag, and now that I have unified the bio and request flags we can easily set it from filesystems. The problem is to emulate it properly on devices that do no actually support the FUA bit. Of which we unfortunately have a lot given that libata by default disables the FUA support even if the device supports. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
