Patch series "Some small improvements for compaction". When I did some compaction testing, I found some small room for improvement as well as some code cleanups. This patch (of 5): The compaction_suitable() will never return values other than COMPACT_SUCCESS, COMPACT_SKIPPED and COMPACT_CONTINUE, so after validation of COMPACT_SUCCESS and COMPACT_SKIPPED, we will never hit other unexpected case. Thus remove the redundant VM_BUG_ON() validation for the return values of compaction_suitable().

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.
