[$] Debugging information for inlined functions
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…
We haven't written up this one. LWN has the full story — the link below goes straight to it.
