From: "D. Wythe" <alibuda@linux.alibaba.com> This patch exports two necessary symbols for registering struct_ops or kfunc with tristate subsystem. Find the corresponding btf_id by name and type with btf_find_by_name_kind(). And find the string in btf by offset with btf_str_by_offset(), used to look up the names of structure members.
