The Power Management and Scheduling in the Linux Kernel Summit, which still goes by the historical acronym OSPM, was held in Cambridge, UK, in mid-April. As has become traditional, the presenters at that event have since written summaries of their sessions, and this work has kindly been made available to LWN for publication. The first day's sessions covered a wide range of topics, including idle-state selection, user-space schedulers with sched_ext, lock-holder preemption, and much more.

Systemd v261 has been released with a long list of changes, including a new cloud "Instance Metadata Service" (IMDS) subsystem, "boot secret" functionality for use on systems that lack a physical TPM, as well as support for the kernel's Live Update Orchestration (LUO) / Kexec Handover (KHO) systems when they are present and enabled. See the release notes for the full list of changes.
