Maybe I've missed it but I cannot find the blktrace output for your
original test and for the test with the first patch posted by Jens
in this thread (the one completely removing the blk_start_queueing()
call), may I ask you if you can point me to them?

From what I understood that patch didn't solve your issue, so the
following ones, that adopt a similar approach, are unlikely to do
any better.

Thank you in advance.
