[$] Debugging information for inlined functions

BPF programs useBPF type format (BTF) debugging information in order todetermine how to interact with functions in the kernel. Specifically, tracing akernel function involves finding its address in the kernel's BTF section - butthat doesn't work for functions that have been inlined, and therefore don't havea single, specific address. Alan Maguire wants to add information about inlinedfunctions to BTF in order to allow them to be traced, and led a session on thattopic at the 2026Linux Storage, Filesystem, Memory-Management, and BPF Summit.
