The amount of times the word "updates" appears in the commits makes me feel much better at my difficulty of choosing succinct and unique commit messages.

Note that those aren't "change commits", but merge commits aggregating large swathes of other changes. And it's not even all merge commits, it's just the merges from Linus' "top lieutenants". But I sympathize. I often spend more time on commit messages than the actual changes...

Indeed - when you go and look at the individual commits, the commit messages tend to be a lot more complex :)

My worst commit-message-to-code-changed ratio is a commit in the kernel with a 1307 char/175 word commit message, and a single character change...

The Kernel Newbies LinuxChanges page hasn't been updated yet, but when it is, it'll be at https://kernelnewbies.org/LinuxChanges .

Should I be worried about Kernel Newbies? The forum is overrun by spam and it looks like the wiki wasn't updated for 4.8.

Still no sign of NVMe "RAID" support: http://marc.info/?t=147709622400002&r=1&w=2

There's already a patch (due for 4.10) to detect and warn about this silliness. Since the Intel guy says that all the systems that shipped with this mode now have firmware updates to allow disabling it, there's very little reason for anyone to implement full support.

Hopefully in the future Intel will think twice before implementing ugly firmware-level hacks to aid in working around limitations of Microsoft's driver stack.

Arguably you could frame that as "best".

Link for the curious?

I've never read the forum but the kernel summaries are fantastic.

What real world impact does changing from (fake) RAID to AHCI have?

kernel 4.9 is the first kernel with full dynamic tracing support built in (beyond the power of systemtap, etc) . We are soon going to see tools like dtrace being built right for Linux.

Im excited for thw future of application development and monitoring on Linux. Imagine a whole bunch of tools more powerful than NewRelic.

It was a fix in PCI error handling on powerpc for a reasonably rare situation where the PCI card doesn't successfully come back up after we reset the slot or the PCI controller...
