[$] Better debugging information for inlined kernel functions

Modern compilers perform a lot of optimizations, which can complicate debugging.Song Liu and Thierry Treyer spoke about a potential improvement toBPF Type Format (BTF) debugging information that could partially combat thatproblem at the 2025 Linux Storage, Filesystem,Memory-Management, and BPF Summit.They want to add information on selectively inlined functions to BTF in order tobetter support tracing tools.Treyer participated remotely.
