The 6.4 kernel has been released
Most of the stuff in my mailbox the last week has been about upcoming things for 6.5, and I already have 15 pull requests pending. I appreciate all you proactive people.But that's for tomorrow. Today we're all busy build-testing the newest kernel release, and checking that it's all good. Right?
Headline features in this release include:
generic iterators for BPF,
the removal of the SELinux runtime disable
knob,
the removal of the SLOB memory allocator,
linear address masking support on Intel
CPUs,
process-level samepage merging control,
support for user trace events,
more infrastructure for writing kernel modules in Rust,
per-VMA locks,
and much more.
See the LWN merge-window summaries (part 1, part 2), and the (in-progress) KernelNewbies 6.4 page for
the details.
