The libdwfl part of the elfutils API falls back to debuginfod lookups internally, so e.g. systemtap had to do nothing to benefit. > Since this series just for the kernel binary, I have to check we > can do something on user-space binaries. It should work identically & transparently. If you're using one of a few key packages of a few mainstream distros, the public debuginfod server may already have the material available. - FChE
