Reporting filesystem features to userspace is currently superblock based. Now we have a general mount-based feature infrastructure, switch to using the xfs_mount rather than the superblock directly. This reduces the size of the function by over 300 bytes. $ size -t fs/xfs/built-in.a text data bss dec hex filename before 1127855 311352 484 1439691 15f7cb (TOTALS) after 1127535 311352 484 1439371 15f68b (TOTALS) Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Darrick J.

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.
