Linux Kernel 4.0 Summary: This release adds support for live patching the kernel code, aimed primarily at fixing security updates without rebooting; DAX, a way to avoid using the kernel cache when filesystems run on systems with persistent memory storage; kasan, a dynamic memory error detector that allows to find use-after-free and out-of-bounds bugs; lazytime, an alternative to relatime, which causes access, modified and changed time updates to only be made in the cache and written to the disk opportunistically; allow overlayfs to have multiple lower layers, support of Parallel NFS server architecture; and dm-crypt CPU scalability improvements. There are also new drivers and many other small improvements.
