[GIT PULL] Block driver changes for 5.6-rc

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

On top of the core changes, though not even strictly needed this time as
they are no dependencies, here are the block driver changes queued up
for 5.6. Like the core side, not a lot of changes here, just two main
items:

- Series of patches (via Coly) with fixes for bcache (Coly, Christoph)

- MD pull request from Song

Please pull!
