Less than two months in development, the Linux 5.14 kernel brings cool new features to the table, such as the merge of the core scheduling functionality to better protect our Linux computers against some Spectre vulnerabilities, the burstable CFS bandwidth controller, or the new mechanism for better controlling resource limits within user namespaces.
Also new is an I/O priority controller for control groups, designed for managing the priority of block-I/O requests generated by the members of each group, a new rate limiter for the split-lock detection feature on the x86 architecture for sleeping processes that create a split lock, as well as a new PCI-over-virtio driver for supporting PCI drivers in user-mode.
