Merge tag 'v4.20-rc6' into for-4.21/block
Pull in v4.20-rc6 to resolve the conflict in NVMe, but also to get the two corruption fixes. We're going to be overhauling the direct dispatch path, and we need to do that on top of the changes we made for that in mainline. Signed-off-by: Jens Axboe <axboe@kernel.dk>
