A future change is going to implement a new devlink command to request a snapshot on demand. As part of this, the logic for handling the snapshot ids will be refactored. To simplify the snapshot id allocation function, move it to a separate function prefixed by `__`. This helper function will assume the lock is held. While no other callers will exist, it simplifies refactoring the logic because there is no need to complicate the function with gotos to handle unlocking on failure.

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.
