Back when Linux 5.1 was released, Linus Torvalds expressed some concern that the Linux 5.2 merge window may have to be extended by a few days as it would conflict with his daughter's graduation, but he has managed still to get 5.2-rc1 out on time.

On top of all the changes queued for Linux 5.2 is an interesting last-minute performance improvement for the vmalloc code.

Late updates to the Linux kernel's perf subsystem introduces support for compressed recording of traces, which can yield a three to five time reduction in file-size.

Con Kolivas has posted his latest patches that re-base his MuQSS scheduler to the new Linux 5.1 kernel.

Following today's disclosure of the new MDS vulnerabilities affecting Intel CPUs, a slew of new Linux kernel stable releases have been issued.

Merged today for the Linux 5.2 kernel are the IOMMU changes that contain some interesting Intel additions.

At first there was some concern over the practicality and use-cases for this driver, the NULL TTY driver has been merged for the Linux 5.2 kernel as part of the TTY/serial updates.

If you make use of Linux kernel live-patching or even just have CONFIG_LIVEPATCH enabled, when switching to Linux 5.2 and building with GCC 9, the performance may be impacted in select workloads.

For those that wait until the first point release before switching over to a new stable series, Linux 5.1.1 is out this morning.

The -Wimplicit-fallthrough compiler flag has been around since GCC 7 for warning over switch fall-through cases where it could lead to potential bugs / unexpected behavior if the programmer inadvertently forgot to add a "break" statement to a case. The Linux kernel is looking to soon enable this warning by default.

The Direct Rendering Manager (DRM) subsystem and driver updates have now been submitted and merged for the in-development Linux 5.2 kernel.

Greg Kroah-Hartman sent in the USB updates on Wednesday for the Linux 5.2 kernel.

While the x86 IRQ changes to the Linux kernel during the merge window periods don't tend to be too interesting for end-users, there is a pleasant change introduced with the Linux 5.2 kernel.

Linus Torvalds happily pulled in the staging subsystem updates today for the Linux 5.2 kernel. While new functionality was added to staging including two new "subsystems", the overall net change for the lines of code is being 111,641 lines of code less.

The HID subsystem updates for the Linux 5.2 kernel have two changes in particular we have been eager to see merged.

Hot off the release of Linux 5.1 from last night, the Free Software Foundation Latin America team has released GNU Linux-libre 5.1-gnu as their sanitized kernel that strips out support for loading binary-only microcode/firmware files, the ability to load binary-only kernel modules, and related code they deem supporting "non-free" software.

Following last night's release of Linux 5.1, the Linux 5.2 merge window is now open. There's already been several pull requests sent in today that Linus is expected to begin acting on shortly.

As was expected, Linus Torvalds just tagged the Linux 5.1 stable kernel.

Linus Torvalds will be celebrating Cinco de Mayo today with the anticipated release of the Linux 5.1 kernel.

Adding to the many changes for Linux 5.2 is Arm's new Komeda DRM/KMS driver being extended to support the Mali D71.

Separate patch series sent out on Wednesday by Intel and AMD Linux developers are continuing work on prepping cgroup infrastructure support around graphics processors.

Assuming Linux 5.1 manages to ship next weekend, the Linux 5.2 merge window will immediately kick off following that release. In our close monitoring of the different development branches in recent weeks, the Linux 5.2 kernel is shaping up to be an outright massive release.

Linus Torvalds has recovered from last week's memma eating and this evening released Linux 5.1-rc7 as the newest test release of the upcoming Linux 5.1 kernel.

VMware can be thanked for one of the performance optimizations coming with the upcoming Linux 5.2 kernel cycle.

A patch series being worked on by Thomas Zimmermann of SUSE allows sharing the TTM memory management implementation between Linux's different DRM frame-buffer drivers.

Queued now into staging for introduction with the upcoming Linux 5.2 kernel cycle is a Generic Counter Interface to allow counter devices/drivers to re-use this common code rather than having to implement redundant code into each of these drivers.

After being in development pretty much this entire decade, KernelShark 1.0 will soon be released as the visualizer around the trace-cmd that wraps Ftrace for internal Linux kernel tracing.

If you have been hit by a bug on Linux 5.1 where your X.Org Server would no longer start or separately where when using VirtIO DRM that XWayland and GNOME Shell would break, fixes have now landed in Linux 5.1 Git.

The Freedreno MSM DRM driver changes have been submitted to DRM-Next ahead of Linux 5.2. MSM provides the Direct Rendering Manager support around Qualcomm Adreno hardware and with this next kernel cycle is continuing to see better Adreno 600 series support.

Linux 5.1-rc6 is larger than the previous release candidate, but he isn't too worried right now about the condition of the upcoming Linux 5.1 kernel.
