682d12148cJosef Bacik <josef@toxicpanda.com> says: Currently if you want to get mount options for a mount and you're using statmount(), you still have to open /proc/mounts to parse the mount options. statmount() does have the ability to store an arbitrary string however, additionally the way we do that is with a seq_file, which is also how we use ->show_options for the individual file systems. Extent statmount() to have a flag for fetching the mount options of a mount. This allows users to not have to parse /proc mount for anything related to a mount. I've extended the existing statmount() test to validate this feature works as expected. As you can tell from the ridiculous amount of silly string parsing, this is a huge win for users and climate change as we will no longer have to waste several cycles parsing strings anymore. Josef Bacik (4): fs: rename show_mnt_opts -> show_vfsmnt_opts fs: add a helper to show all the options for a mount fs: export mount options via statmount() sefltests: extend the statmount test for mount options fs/internal.h | 5 + fs/namespace.c | 7 + fs/proc_namespace.c | 29 ++-- include/uapi/linux/mount.h | 3 +- .../filesystems/statmount/statmount_test.c | 131 +++++++++++++++++- 5 files changed, 164 insertions(+), 11 deletions(-) Link: https://lore.kernel.org/r/cover.1719257716.git.josef@toxicpanda.com 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.
