/**
 * struct bpf_struct_ops - A structure of callbacks allowing a subsystem to
 *			   define a BPF_MAP_TYPE_STRUCT_OPS map type composed
 *			   of BPF_PROG_TYPE_STRUCT_OPS progs.
 * @verifier_ops: A structure of callbacks that are invoked by the verifier
 *		  when determining whether the struct_ops progs in the
 *		  struct_ops map are valid.
 * @init: A callback that is invoked a single time, and before any other
 *	  callback, to initialize the structure. A nonzero return value means
 *	  the subsystem could not be initialized.
 * @check_member: When defined, a callback invoked by the verifier to allow
 *		  the subsystem to determine if an entry in the struct_ops map
 *		  is valid. A nonzero return value means that the map is
 *		  invalid and should be rejected by the verifier.
 * @init_member: A callback that is invoked for each member of the struct_ops
 *		 map to allow the subsystem to initialize the member. A nonzero
 *		 value means the member could not be initialized. This callback
 *		 is exclusive with the @type, @type_id, @value_type, and
 *		 @value_id fields.
 * @reg: A callback that is invoked when the struct_ops map has been
 *	 initialized and is being attached to. Zero means the struct_ops map
 *	 has been successfully registered and is live. A nonzero return value
 *	 means the struct_ops map could not be registered.
 * @unreg: A callback that is invoked when the struct_ops map should be
 *	   unregistered.
 * @update: A callback that is invoked when the live struct_ops map is being
 *	    updated to contain new values. This callback is only invoked when
 *	    the struct_ops map is loaded with BPF_F_LINK. If not defined, the
 *	    it is assumed that the struct_ops map cannot be updated.
 * @validate: A callback that is invoked after all of the members have been
 *	      initialized. This callback should perform static checks on the
 *	      map, meaning that it should either fail or succeed
 *	      deterministically. A struct_ops map that has been validated may
 *	      not necessarily succeed in being registered if the call to @reg
 *	      fails. For example, a valid struct_ops map may be loaded, but
 *	      then fail to be registered due to there being another active
 *	      struct_ops map on the system in the subsystem already. For this
 *	      reason, if this callback is not defined, the check is skipped as
 *	      the struct_ops map will have final verification performed in
 *	      @reg.
 * @type: BTF type.
 * @value_type: Value type.
 * @name: The name of the struct bpf_struct_ops object.
 * @func_models: Func models
 * @type_id: BTF type id.
 * @value_id: BTF value id.
