[GIT PULL] Block fixes for 4.20-rc6

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

Let's try this again... We're finally happy with the DM livelock issue,
and it's also passed overnight testing and the corruption regression
test. The end result is much nicer now too, which is great. Outside of
that fix, there's a pull request for NVMe with two small fixes, and a
regression fix for BFQ from this merge window. The BFQ fix looks bigger
than it is, it's 90% comment updates.

Please pull!
