Linux 5.4 Released

'Linux 5.4 has been released, featuring the new 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, support for the
exfat file system and removing the experimental status of the erofs
file system; a new haltpoll cpuidle driver and governor that greatly
improves performance for virtualized guests wanting to do guest-side
polling in the idle loop; and blk-iocost, a new cgroup controller that
attempts to calculate more accurately the cost of IO. As always, many
other new drivers and improvements can be found in the changelog.'
