As you've probably gathered, I've been preoccupied with Covid-19 issues delaying any attempt to stay in sync with the latest kernel. I didn't even know there was a new one till recently.
Here's what I've been busy with:

I'll be back when things stop being so crazy.

Please take care,

Happy new decade.
Happy new decade everyone.
Here's an interesting blogpost a few people on IRC have pointed out to me. Best save reading it for after you've sobered up in the new year ☺
https://probablydance.com/2019/12/30/measuring-mutexes-spinlocks-and-how-bad-the-linux-scheduler-really-is
The anecdotal video performance part of that whole post may well be the most interesting part of it, but there's definitely food for thought there regarding locking primitives and MuQSS's performance. I've pointed out in a comment (yet to be published) to the author that yield is configurable on MuQSS and use of it is likely responsible for the poor performance of the sub-benchmarks involving it. Either way it makes for interesting reading and I anticipate a mainline mutex and especially spinlock performance speed chase in the near future. This can only lead to good things for everyone.
