commit 104eef133fd9c17e4dc28bf43f592a86f26d8a59 upstream.
After the recent conversion to the new mount API, there is a warning
when building hostfs (which may be upgraded to an error via
CONFIG_WERROR=y):
fs/hostfs/hostfs_kern.c: In function 'hostfs_fill_super':
fs/hostfs/hostfs_kern.c:942:27: warning: initialization discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
942 | char *host_root = fc->source;
| ^~
Add the 'const' qualifier, as host_root will not be modified after its
assignment. Move the assignment to keep the existing reverse Christmas
tree order intact.

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.
