Pull block fixes from Jens Axboe:
 "A bit earlier in the week as usual, but there's a fix here that should
  go in sooner rather than later.

  Under a combination of circumstance, the direct issue path in blk-mq
  could corrupt data. This wasn't easy to hit, but the ones that are
  affected by it, seem to hit it pretty easily. Full explanation in the
  patch. None of the regular filesystem and storage testing has
  triggered it, even though it's been around since 4.19-rc1.

  Outside of that, whitelist trim tweak for certain Samsung devices for
  libata"
