A New Mount API - Christian Brauner, Canonical
Almost since its inception Linux had a single syscall for creating and changing mounts. It had to cover mounting of real filesystems, bind mounts, remounting to change superblock options, remounting to change mount-specific options, mount propagation and other filesystem specific options. This caused the syscall to be overloaded. The old syscalls also lacked desirable properties such as being able to apply mount options to a whole mount tree instead of just a single mount. The new mount api splits the single mount syscall into multiple syscalls effectively allowing to create a mount context that can be configured and interacted with before even making the mount visible in the filesystem hierarchy. In this talk we will cover the layout of the new mount api, how it can be used to replace the old mount api, and specifically focus on new features such as detached mounts, or mount notifications and why it is desirable for userspace to start switching to it rather sooner than later. We will also take the time to look at future extensions such as supervised mounts.

Panel Discussion: Outreachy Linux Kernel Internship Report - Helen Koike, Outreachy / Collabora; Jules Irenge, Lourdes Pedrajas, Kaaira Gupta & Shreeya Patel & Briana Oursler, Outreachy
Come learn about the amazing work our kernel interns have accomplished! Outreachy provides 3 months paid internships for people from groups traditionally underrepresented in tech to work on open source projects. The panel will present the following Linux kernel projects: * Briana Oursler: Improve and extend kernel networking self-tests running in namespaces * Jules Irenge: Fix lock-related warnings reported by sparse for core kernel code * Kaaira Gupta: Linux Media and libcamera: multi stream test support with VIMC * Lourdes Pedrajas: Improve and extend kernel networking self-tests running in namespaces * Shreeya Patel: Add SOF-Fuzzer support for i.MX8 platform
