函数名称：Used for ptr, array and struct/union type members.* int, enum and modifier types have their specific callback functions.

函数原型：static int btf_generic_check_kflag_member(struct btf_verifier_env *env, const struct btf_type *struct_type, const struct btf_member *member, const struct btf_type *member_type)

返回类型：int

参数：

类型参数名称
struct btf_verifier_env *env
const struct btf_type *struct_type
const struct btf_member *member
const struct btf_type *member_type
1199  如果If the struct/union type info kind_flag is set, the* following two macros are used to access bitfield_size* and bit_offset from btf_member.offset.(If the type info kind_flag is set, the btf_member offset* contains both member bitfield size and bit offset. The* bitfield size is set for bitfield members. If the type* info kind_flag is not set, the offset contains only bit* offset.)则
1200  btf_verifier_log_member(env, struct_type, member, "Invalid member bitfield_size")
1202  返回:负EINVAL
1208  返回:check_member(env, struct_type, member, member_type)
