Although there are only two callers, we are going to add some members for scrub_block in the incoming patches. Factoring out the initialization code will make later expansion easier. One thing to note is, even scrub_handle_errored_block() doesn't utilize scrub_block::refs, we still use alloc_scrub_block() to initialize sblock::ref, allowing us to use scrub_block_put() to do cleanup.

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.
