[$] Debugging information for inlined functions

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