Linus Torvalds has released the 5.12
kernel. "Thanks to everybody who made last week very calm indeed, which just
makes me feel much happier about the final 5.12 release."
Headline features in 5.12 include
the removal of a number of obsolete, (mostly) 32-bit Arm subarchitectures,
atomic
instructions for BPF,
conditional file lookups with LOOKUP_CACHED,
support for zoned block devices in the Btrfs
filesystem,
threaded NAPI polling in the network stack,
filesystem ID mapping,
support for building the kernel with Clang link-time
optimization,
the KFENCE
kernel-debugging tool, and more. See the LWN merge-window summaries
(part 1, part 2) and the (in-progress) KernelNewbies 5.12 page for
more information.
