Čestmír Kalina approved merge request !1066: owners: Add restartable sequence at Red Hat / centos-stream / src / kernel / documentation

2026-03-03T15:39:21Z

Restartable sequence is a kernel feature that enables userspace code (like glibc) to handle percpu variables and even implement userspace spinlocks. It complements futex that enables userspace mutex. Add that as part of the locking component.
