Jeff Layton <jlayton@kernel.org> says: We had some recent queries internally asking how to use the new statmount() and listmount() interfaces. I was doing some other work in this area, so I whipped up this tool. My hope is that this will represent something of a "rosetta stone" for how to translate between mountinfo and statmount(), and an example for other people looking to use the new interfaces. It may also be possible to use this as the basis for a listmount() and statmount() testcase. We can call this program, and compare its output to the mountinfo file. The second patch adds security mount options to the existing mnt_opts in the statmount() interface, which I think is the final missing piece here. The alternative to doing that would be to add a new string field for that, but I'm not sure that's worthwhile. * patches from https://lore.kernel.org/r/20241115-statmount-v2-0-cd29aeff9cbb@kernel.org: fs: prepend statmount.mnt_opts string with security_sb_mnt_opts() samples: add a mountinfo program to demonstrate statmount()/listmount() Link: https://lore.kernel.org/r/20241115-statmount-v2-0-cd29aeff9cbb@kernel.org Signed-off-by: Christian Brauner <brauner@kernel.org>
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 reStructuredText 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.
