Squeezing More Performance Out Of The Linux Kernel With Clang + LTO

Squeezing More Performance Out Of The Linux Kernel With Clang + LTO: With the Linux 5.12 kernel bringing support for building the kernel with link-time optimizations (LTO) when using the LLVM Clang compiler, here are some benchmarks looking at that performance impact as well as more generally seeing how the LLVM Clang compiler performance is looking when building the Linux kernel relative to GCC.
