... and copy the data from it into sbinfo in the callers. For use by remount we need to keep track whether there'd been options setting max_inodes, max_blocks and huge resp. and do the sanity checks (and copying) only if such options had been seen. uid/gid/mode is ignored by remount and NULL mpol is already explicitly treated as "ignore it", so we don't need to keep track of those. Note: theoretically, mpol_parse_string() may return NULL not in case of error (for default policy), so the assumption that NULL mpol means "change nothing" is incorrect. However, that's the mainline behaviour and any changes belong in a separate patch. If we go for that, we'll need to keep track of having encountered mpol= option too.

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.
