Linus has released the 6.12 kernel.
“No strange surprises this last week, so we’re sticking to the regular
release schedule, and that obviously means that the merge window opens
tomorrow.“.

Headline features in this release include:

support for the Arm
permission overlay extension,
better compile-time control over which Spectre mitigations to employ,
the last pieces of realtime preemption support,
the realtime deadline server mechanism,
more EEVDF scheduler development,
the extensible scheduler class,
the device memory TCP work,
use of static calls in the security-module
subsystem,
the integrity
policy enforcement security module,
the ability to handle devices with a block size larger than the system page
size in the XFS filesystem,
and more.
See the LWN merge-window summaries
(part 1, part 2) and the KernelNewbies 6.12 page for
