Pull fixes from moby/storage

[redbaron]

Sorry if I misunderstand intention of this project, looks like it is aiming to implement docker features in a docker-independent way, yet it reuses a lot of docker code.

There were few fixes done do docker graphdrivers year ago, which I can find in a current codebase, which is worrying, how this project is meant to be supported and go forward? If there is no development resources allocated to evolve storage drivers, maybe worth reexporting everything from docker graphdrivers?

Example of missing PRs are :

• Fixes Issue # 23418: Race condition between device deferred removal and resume device. moby/moby#23497
• devmapper: Set xfs max_retries to 0 upon ENOSPC moby/moby#26212

How timely. We have been working on forward patching stuff from moby this week.
#98
#105
#100

So yes we plan on staying up to date with any changes/bug fixes there.

Right now we have been concentrating on Overlay driver (overlay2 in Moby). But we plan on adding more support for devicemapper and perhaps replacing it with a new lvm based driver going forward.

These have been all back ported, I believe.
