Embedded vmlinuxinline BTF supports read-only mmap().Provide runtime support for a module-delivered vmlinux inline BTFcarrier. Its link record binds the carrier module name, BTF size, andSHA-256 digest to the running kernel before its data is made availablethrough a lazy vmlinux.inline sysfs attribute. The carrier is handledbefore ordinary module BTF registration, so its incidental .BTF data isnot exposed.Make CONFIG_DEBUG_INFO_BTF_INLINE tristate. When configured as amodule, retain vmlinux final split inline BTF forbtf_vmlinux_inline.ko instead of embedding it in vmlinux.Reserve .BTF.inline.link in vmlinux and extend the finalresolve_btfids patch pass to bind btf_vmlinux_inline to the rawvmlinux.BTF.inline payload. This preserves the normal built-inconfiguration while allowing the large inline BTF payload to load ondemand.Normal module inline BTF is handled separately, after itsreferences have been relocated against the final module BTF.Signed-off-by: Alan Maguire <alan.maguire@oracle.com>Signed-off-by: Alexei Starovoitov <ast@kernel.org>Link: https://patch.msgid.link/20261009112324.1442319-4-alan.maguire@oracle.com List of files: /linux/kernel/bpf/btf_vmlinux_inline.c Fri, 09 Oct 2026 13:23:20 +0200 Alan Maguire <alan.maguire@oracle.com>
