Linus Torvalds announced on the Linux Kernel mailing list that the Linux Kernel 5.4 has been officially released! Linux Kernel 5.4 includes the kernel lockdown mode, intended to strengthen the boundary between UID 0 and the kernel; virtio-fs, a high-performance virtio driver which allows a virtualized guest to mount a directory that has been exported on the host; fs-verity, for detecting file tampering, like dm-verity, but works on files rather than block devices; dm-clone, which allows live cloning of dm targets; two new madvise() flags for improved app memory management on Android, support for new Intel/AMD GPUs.
