Linux kernel source tree

In the BPF token example, the fsopen() syscall is called as privileged user. This is unneeded because fsopen() can be called also as unprivileged user from the user namespace. As the `fs_fd` file descriptor which was sent back and forth is still the same, keep it open instead of cloning and closing it twice via SCM_RIGHTS. cfr. https://github.com/systemd/systemd/pull/36134 Signed-off-by: Matteo Croce <teknoraver@meta.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Acked-by: Christian Brauner <brauner@kernel.org> Link: https://lore.kernel.org/bpf/20250701183123.31781-1-technoboy85@gmail.com |

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.
