1) docker create / run / start: this would create a snapshot device and mounts it onto the filesystem.
So the first time GET operation is called. it will create the rootfs directory and return the path to rootfs
2) Now when I do docker commit. It will call the GET operation second time. This time the refcount will check
that the count > 1 (count=2). so the rootfs already exists, it will just return the path to rootfs.
Earlier it was just returning the mp: /var/lib/docker/devicemapper/mnt/{ID} and hence the inconsistent paths error.

This environment variable is no longer
needed in Go 1.6 (as it's not the default).
Removed this environment variable from
all Dockerfiles except the Dockerfile.s390x,
which is still using gcc 5.3 (Go 1.5)

This fix fixes an error in documentation (dockerd.md). In the
example given by dockerd.md, the option `cluster-store-opts`
is assigned with an array but this option can only be assigned
as a map.

This fix tries to address the issue raised in #22420. When
`--tmpfs` is specified with `/tmp`, the default value is
`rw,nosuid,nodev,noexec,relatime,size=65536k`. When `--tmpfs`
is specified with `/tmp:rw`, then the value changed to
`rw,nosuid,nodev,noexec,relatime`.
The reason for such an inconsistency is because docker tries
to add `size=65536k` option only when user provides no option.
This fix tries to address this issue by always pre-progating
`size=65536k` along with `rw,nosuid,nodev,noexec,relatime`.
If user provides a different value (e.g., `size=8192k`), it
will override the `size=65536k` anyway since the combined
options will be parsed and merged to remove any duplicates.
Additional test cases have been added to cover the changes
in this fix.
This fix fixes#22420.

Since 1.9, the following short variant options have been
deprecated in favor of their long variants:
`docker run -c (--cpu-shares)`
`docker build -c (--cpu-shares)`
`docker create -c (--cpu-shares)`
`docker update -c (--cpu-shares)`
However, `-c` is still widely used and is considered as
a convenient option for swarm (see #16271).
This fix undeprecated the command line short
variant options of `-c` and updated the deprecated.md.
