Re: [PATCH v5 0/10] block: per-distpatch_queue flush machinery

[Christoph Hellwig]

 To review this properly I had to actually squatch patches 2-4 and 6-9
into a single patch to read nicely over it, the result is attached below.

That one has one minor issue in __blk_drain_queue where a newly added
indent uses 4 spaces instead of tabs, but otherwise everything in this
series looks fine to me and passes sanity testing with scsi-mq.
