Both scan_sleep_millisecs_store() and alloc_sleep_millisecs_store() perform the same operations: parse the input value, update their respective sleep interval, reset khugepaged_sleep_expire, and wake up the khugepaged thread. Factor out this duplicated logic into a helper function __sleep_millisecs_store(), and simplify both store functions. No functional change intended.

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 reStructuredText 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.
