Nathan Scott f07c225036 [XFS] Improve xfsbufd delayed write submission patterns, after blktrace ... analysis. Under a sequential create+allocate workload, blktrace reported backward writes being issued by xfsbufd, and frequent inappropriate queue unplugs. We now insert at the tail when moving from the delwri lists to the temp lists, which maintains correct ordering, and we avoid unplugging queues deep in the submit paths when we'd shortly do it at a higher level anyway. blktrace now reports much healthier write patterns from xfsbufd for this workload (and likely many others).
