[GIT PULL v2] Final block fixes for 5.10

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

Mike and Song looked into the warning case, and thankfully it appears
the fix was pretty trivial - we can just change the md device chunk type
to unsigned int to get rid of it. They cannot currently be < 0, and
nobody is checking for that either.

That said, this should be it for 5.10. We're reverting the discard
changes as the corruption reports came in very late, and there's just no
time to attempt to deal with it at this point. Reverting the changes in
question is the right call for 5.10.

Please pull!
