The 5.4 kernel has been released
Linus has released the 5.4 kernel.
"
Not a lot happened this last week, which is just how I like it". Significant features in this release include the haltpoll CPU governor, the iocost (formerly io.weight) I/O controller, the EROFS filesystem, an implementation of the exFAT filesystem that may yet be superseded by a better version, the fs-verity file integrity mechanism, support for the BPF compile once, run everywhere mechanism, the dm-clone device mapper target, the virtiofs filesystem, kernel lockdown support (at last), kernel symbol namespaces, and a new random-number generator meant to solve the early-boot entropy problem. See the KernelNewbies 5.4 page for a lot more details.
