to_mp() was first introduced with the following commit: 'commit801cc4e17a("xfs: debug mode forced buffered write failure")' But the user of to_mp() was removed by below commit: 'commitf8c47250ba("xfs: convert drop_writes to use the errortag mechanism")' So kernel build with clang throws below warning message: fs/xfs/xfs_sysfs.c:72:1: warning: unused function 'to_mp' [-Wunused-function] to_mp(struct kobject *kobject) Hence to_mp() might be removed safely to get rid of warning message.

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.
