With this patch I wasn't able to trigger per-CPU-related warning.
Also, for 8th patch you've written:
I have sent one delta patch in list, which will only call

That looks not bad, and thanks for your test!
Could you try
Tested against v4.13-rc7. With this patchset it looks like I/O doesn't hang,
but once (just once, not each time) I've got the following stacktrace on
resume:

Since I'm in CC, does this series aim to replace 2 patches I've tested before:
blk-mq: add requests in the tail of hctx->dispatch
blk-mq: align to legacy's implementation of blk_execute_rq
?

Yeah, this solution is
The current SCSI quiesce isn't safe and easy to trigger I/O deadlock.
Once SCSI device is put into QUIESCE, no new request except for RQF_PREEMPT
can be dispatched to SCSI successfully, and scsi_device_quiesce() just simply
waits for completion of I/Os dispatched to SCSI stack. It isn't enough at
7 matches
