[ Upstream commit da63dc84befaa9e6079a0bc363ff0eaa975f9073 ] Compaction sysfs file is created via compaction_register_node in register_node. But we forgot to remove it in unregister_node. Thus compaction sysfs file is leaked. Using compaction_unregister_node to fix this issue.

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.
