> Linux kernel 6.18 is now available for download, as [2]announced today by Linus Torvalds himself, featuring enhanced hardware support through new and updated drivers, improvements to file systems and networking, and more. Highlights of Linux 6.18 include the removal of the Bcachefs file system, support for the Rust Binder driver, a new dm-pcache device-mapper target to enable persistent memory as a cache for slower block devices, and a new microcode= command-line option to control the microcode loader's behavior on x86 platforms. Linux kernel 6.18 also extends the support for file handles to kernel namespaces, implements initial 'block size > page size' support for the Btrfs file system, adds PTW feature detection on new hardware for LoongArch KVM, and adds support for running the kernel as a guest on FreeBSD's Bhyve hypervisor.
