Later patches will introduce feature set bits to on-disk super block and increase super block version. Current code in read_super() which reads common part of super block for version BCACHE_SB_VERSION_CDEV and version BCACHE_SB_VERSION_CDEV_WITH_UUID will be shared with the new version. Therefore this patch moves the reusable part into read_super_common(), this preparation patch will make later patches more simplier and only focus on new feature set bits.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
