After being in development for more than two months, Linux kernel 5.19 is finally here and introduces support for ZSTD-compressed firmware files, support for AMD’s Secure Nested Paging feature, a new user-space API for managing MultiPath TCP (MPTCP) flows, initial support for Loongson’s “LoongArch” RISC ISA CPU architecture, as well as support for the ARM Scalable Matrix Extension (SME).

Also new support for supervisor-mode page-based memory types and the ability to run 32-bit binaries on 64-bit systems for RISC-V architectures, support for SMP coprocessors, KCSAN, and hibernation to the Xtensa architecture, a new generic ticket spinlock type to add support for full qspinlock implementation in various architectures like RISC-V, OpenRISC, and C-SKY, and a new FAN_MARK_EVICTABLE flag to the fanotify mechanism to avoid pinning the targeted inode in the inode cache.
