Linus has released the 6.8 kernel.

So it took a bit longer for the commit counts to come down this
release than I tend to prefer, but a lot of that seemed to be about
various selftest updates (networking in particular) rather than any
actual real sign of problems. And the last two weeks have been
pretty quiet, so I feel there’s no real reason to delay 6.8.

Significant changes in this release include
the deadline servers scheduling feature,
support for memory-management
auto-tuning in DAMON,
the large anonymous folios feature,
the kernel
samepage merging advisor,
the ability to prevent writes to block
devices containing mounted filesystems,
the listmount() and
statmount() system calls,
the first
device driver written in Rust,
the removal
of the (never finished) bpfilter
packet-filtering system,
three new system calls for managing Linux
security modules,
the BPF token mechanism for fine-grained
control over BPF permissions,
support for data-type profiling in the
perf tool,
guest-first memory for KVM virtualization,
the Intel Xe graphics driver,
and a lot more. See the LWN merge-window summaries
(part 1,
part 2) for more information.
