"This includes the remaining patches to complete the basic support for
CXL type2 (accelerators) drivers by the CXL core. A set of unit
testing support to catch regressions for the CXL core type2 exported
functions has also been added. The actual CXL type 2 driver support
for the AMD Solarflare NIC driver has been picked up by net-dev.
A set of preparatory patches has been picked up from the CXL port
error handling series in order to reduce the number of patches in that
series for review. The rest of that series is getting close to be
merged but was not ready for the 7.3 merge window.
There are also a number of misc patches and a large number of bug
fixes against pre-existing issues flagged by sashiko reviews as
contributors post new patches on the mailing list. We will continue to
work through the sashiko raised issues as they show up."

"Most of this cycle completes the enqueue-path support for hierarchical

sub-scheduler owns all scheduling decisions for its tasks on those
CPUs.

scheduling fixes that were completed too late for the v7.2 release and

affinities stale when the controller is disabled in a threaded

apply stale state, and the deadline task count could get corrupted by
concurrent updates, skewing SCHED_DEADLINE admission decisions.
- Memory binding bug fixes: which node masks get applied differed
between the binding update paths, and tasks cloned with
CLONE_INTO_CGROUP skipped rebinding entirely. Rebinding also now runs
once per process instead of repeating for every thread sharing the
mm.

"One of the 'small improvements all over the place' releases for us.
It's hard to draw any direct comparisons because summer vacations
disrupted our patch processing (and presumably - generation) quite a
bit.
Quick and dirty count suggests we (Paolo and I) merged a very similar
number of net (632) and net-next (648) patches. This is not telling
the full story either because 1/3 to 1/2 of the net-next patches also
*seem* like AI-driven low priority fixes, cleanups and clarifications.
We are completely overwhelmed, of course. The glimmer of hope is that
we secured sufficient LLM budget and access (thank you Meta!) to run
reviews with multiple frontier models on each patch. This eliminates
some hallucinations. That said, in terms of review, the LLMs can only
do so much.
