\o/ Linus merged the bulk of the #PREEMPT_RT locking infrastructure for proper #realtime support to #Linux mainline, which thus will be a part of #kernel 5.15: git.kernel.org/torvalds/c/e5e…

Congrats to Thomas and everyone involved!

To quote: ```[…] The underlying concepts… …of this code have been in use in PREEMPT_RT for way more than a decade. The code has been refactored several times over the years and this final incarnation has been optimized once again to be as non-intrusive as possible, i.e. the RT specific parts are mostly isolated.

I need 4 tweets for the highlights in main #network merge for #Linux 5.10:

* #BPF programs can be shipped with the #kernel and loaded on boot via the User Mode Driver mechan. git.kernel.org/torvalds/c/0bc…

* sleepable BPF programs
git.kernel.org/torvalds/c/104…
lwn.net/Articles/82541…

(1/4) * BPF Type Format (BTF) support for type and enum discovery & support for using BTF within the kernel itself
git.kernel.org/torvalds/c/98b…

* add and consume TCP header options in BPF programs, allowing easy experim. and deployment-specific TCP option use
git.kernel.org/torvalds/c/0bc…
