Kumar Kartikeya Dwivedi 42ba130807 bpf: Make btf_find_field more generic ... Next commit introduces field type 'kptr' whose kind will not be struct, but pointer, and it will not be limited to one offset, but multiple ones. Make existing btf_find_struct_field and btf_find_datasec_var functions amenable to use for finding kptrs in map value, by moving spin_lock and timer specific checks into their own function. The alignment, and name are checked before the function is called, so it is the last point where we can skip field or return an error before the next loop iteration happens. Size of the field and type is meant to be checked inside the function.
