Hello:

If CONFIG_DEBUG_INFO_BTF_INLINE=y|m, add the "inline" BTF feature
and encode inline site info in BTF alongside standard BTF data.
resolve_btfids will then partition into non- and inline-related
info and split BTF will be used to store inline info in a
.BTF.inline section in vmlinux and modules.  For
CONFIG_DEBUG_INFO_BTF=m, vmlinux inline info will be stored
in btf_vmlinux_inline.ko and will be loaded on-demand if used
via /sys/kernel/btf/vmlinux.inline.  A .BTF.inline.link section
in vmlinux stores the module name, the SHA of the BTF and the
size so that even without loading the kernel can size the
sysfs representation correctly.  This approach is based on [1]
and the .BTF.inline.link section is modeled on .GNU_debuglink.
