Google transitioned its data center fleet to run Clang built kernels in 2021, and Meta did so as well in 2022. Meta talked about this at LPC 2022 at a talk titled Kernel Live Patching at Scale. These were important milestones for building the kernel with Clang. Making note of them helps improve confidence in the project.
