Well, can a 1400073 [2022-10-17..2022-12-09] HOST kernel running a
1400079 [2023-02-08..2023-02-10] jail that is using new KBI
material not in the older kernel (CPU_WHICH_TIDPID) have problems? :

Similarly, can a 1400073 [2022-10-17..2022-12-09] HOST kernel running a
13.2-PRERELEASE 1301511 [2023-01-10..2023-02-10] jail that is using new

(Looks to me like CPU_WHICH_TIDPID use for 13.* has to
require 13.2+ .)
