Merge branch 'bpf-static-linker-fix-linking-duplicate-extern-functions'
Eric Long via says:
====================
BPF static linker: fix linking duplicate extern functions
Currently, if `bpftool gen object` tries to link two objects that
contains the same extern function prototype, libbpf will try to get
their (non-existent) size by calling bpf__resolve_size like extern
variables and fail with:
libbpf: global 'whatever': failed to resolve size of underlying type: -22
This should not be the case, and this series adds conditions to update
size only when the BTF kind is not function.
Fixes: a46349227cd8 ("libbpf: Add linker extern resolution support for functions and global variables")
