Here are backports of some fixes to the 4.14 stable branch.

I tested the blktrace fix with the script referenced in the commit
message.

I wasn't able to test the i40e changes (no hardware and no reproducer
available).

Ben.

What is "this" and what is "the best yet"?  Which patch(s) here are you
referring to in your context-less top-post?  :)

thanks,

Sorry, I had to send the email as I did as I was not able to access a
computer to properly reply on time (local hurricane cut power off and
internet for a while), and in proper form, and so I figured it would be
more prudent to request to *yield* merging until I do proper review.

Given I am replying to patches which I authored I figured you could
at least infer the email was about blktrace... so you are really
exagerating contextless comment here.

Anyway, you can carry on with the fix for blktrace to be merged,
the concerne would be if you decide to backport the other important
fix "block: revert back to synchronous request_queue removal".

That is, do not merge that loosely, even if you don't see any issues.
This requires a bit more work to backport.
