It is perhaps unusual to have a kernel tracing developer leading a
filesystem session, Steven Rostedt said, at the beginning of such a session at the
2022 Linux Storage,
Filesystem, Memory-management and BPF Summit (LSFMM). But he was doing
so to
try to find a good way to dynamically allocate kernel data structures
for some of the pseudo-filesystems, such as sysfs, debugfs, and tracefs,
in the kernel.
Avoiding static allocations would save memory, especially on systems
that are not actually using any of the files in those filesystems.

Software Freedom Conservancy (SFC)
has
announced
that it succeeded with its motion in US Federal Court to send the case back
to California, where it was originally filed. The suit was
filed
in October 2021 by SFC, as an owner of Vizio televisions, to get
the company to comply with the GPL on some of the code in the TVs. Back in November, Vizio had
asked to move the
case to Federal Court, because the GPL is only a copyright license
(which is a dispute handled at the Federal level) and not a contract (that
could be adjudicated in state court). Friday's ruling disagreed with that premise:
The May 13 ruling by the Honorable Josephine L. Staton stated that the
claim from Software Freedom Conservancy succeeded in the "extra element
test" and was not preempted by copyright claims, and the court finds "that
the enforcement of 'an additional contractual promise separate and distinct
from any rights provided by the copyright laws' amounts to an 'extra
element,' and therefore, SFC's claims are not preempted."
"The ruling is a watershed moment in the history of copyleft
licensing. This ruling shows that the GPL agreements function both as
copyright licenses and as contractual agreements," says Karen M. Sandler,
executive director of Software Freedom Conservancy. Sandler noted that many
in the Free and Open Source Software (FOSS) legal community argue
incorrectly that the GPL and other copyleft licenses only function as
copyright licenses.

A new helper library for network filesystems, called netfslib, was the subject
of a filesystem session at the
2022 Linux Storage,
Filesystem, Memory-management and BPF Summit (LSFMM). David Howells
developed
netfslib, which was merged for 5.13 a year ago, and led the session.
Some filesystems, like AFS and Ceph, are already using some of the services
that netfslib provides, while others are starting to look into it.

The
5.18-rc7 kernel prepatch has been
released for testing. Linus says: "So things continue to be fairly
calm, and as such this is likely the last rc before 5.18 unless something
bad happens next week".

Memory reclaim in Linux is largely a reactive practice; the kernel tries to
find memory it can repurpose in response to the amount of free memory
falling too low. Developers have often wondered if a proactive reclaim
mechanism might lead to better performance, for some workloads at least,
and optimal use of tiered-memory systems will likely require more active
reclamation of memory as well. At the
2022 Linux Storage,
Filesystem, Memory-management and BPF Summit (LSFMM), Davidlohr Bueso
led a brief session on the topic.

Compute Express
Link (CXL) is an upcoming memory technology that is clearly on the
minds of Linux memory-management developers; there were five sessions
dedicated to the topic at the
2022 Linux Storage,
Filesystem, Memory-management and BPF Summit (LSFMM). The first three
sessions, on May 3, covered various aspects of memory management in the
presence of CXL. It seems that
CXL may bring some welcome capabilities, especially for cloud-service
providers, but that will come at the cost of some headaches on the
kernel-development side.

Many types of kernel changes can be hammered into shape on the mailing
lists. There are certain types of patches, however, that have a hard time getting to
the finish line that way; they are sufficiently large and invasive that
they need an actual gathering of the developers involved. The
multi-generational LRU work (MGLRU) falls into this
category, which is why it was the subject of a full-hour session at the
2022 Linux Storage,
Filesystem, Memory-management and BPF Summit (LSFMM). The discussion
held there may well have opened the doors for this code to be merged in the
near future.

The kernel's "direct map" makes the entirety of a system's physical memory
available in the kernel's virtual address space. Normally, huge pages are used for
this mapping, making it relatively efficient to access. Increasingly,
though, there is a need to carve some pages out of the direct map; this
splits up those huge pages and makes the system as a whole less efficient.
During a memory-management session at the
2022
Linux Storage, Filesystem, Memory-management and BPF Summit (LSFMM),
Mike Rapoport led a session on direct-map fragmentation and how it might be
avoided.

On May 10, Red Hat
announced the release of Red Hat Enterprise Linux 9 (RHEL 9). Not surprisingly, the announcement is rather buzzword-heavy and full of marketing, though there are some technical details scattered in it. The release notes for the RHEL 9 beta are
available, which have a lot more information. "The platform will be generally available in the coming weeks."
Building on decades of relentless innovation, the latest version of the world’s leading enterprise Linux platform is the
first production release built from CentOS Stream, the continuously delivered Linux distribution that tracks just ahead of Red Hat Enterprise Linux. This approach helps the broader Red Hat Enterprise Linux ecosystem, from partners to customers to independent users, provide feedback, code and feature updates to the world’s leading enterprise Linux platform.

Phoronix
reports
that the days of proprietary NVIDIA graphics drivers are coming to a close.
NVIDIA's open kernel modules is already considered "production
ready, opt-in" for data center GPUs. For GeForce and workstation
GPUs, the open kernel module code is considered "alpha quality" but
will be ramped up moving forward with future releases. NVIDIA has
already deprecated the monolithic kernel module approach for their
data center GPU support to focus on this open kernel driver
solution (and their existing proprietary kernel module using the
GSP). Only Turing and newer GPUs will be supported by this
open-source kernel driver. Pre-Turing GPUs are left to using the
existing proprietary kernel drivers or the Nouveau DRM driver for
that matter.
The user-space code remains proprietary, though, which could inhibit the
eventual merging of this code into the mainline kernel.
Update: here is NVIDIA's
press release on the new drivers.

In a filesystem session at the
2022 Linux Storage,
Filesystem, Memory-management and BPF Summit (LSFMM), Ted Ts'o brought
up the subject of filesystems that get resized frequently and whether the
default parameters for filesystem creation should change as a result. It
stems from a conversation that he had with XFS developer Darrick
Wong, who is experiencing some the same challenges as ext4 in this area.
He outlined the problem and how it comes about, then led the discussion on
ways to perhaps address it.

Out-of-memory (OOM) situations are dreaded by users, system administrators,
and kernel developers alike. Usually, all that is known is that a lot of
memory is being used somewhere and the system has run out, but the kernel provides little help to
anybody trying to figure out where the memory has gone. In a memory-management
session at the
2022
Linux Storage, Filesystem, Memory-management and BPF Summit (LSFMM),
Kent Overstreet asked what could be done to improve OOM reports and reduce
the pain for all involved.
