I would like very much to get v38 or v39 of the LSM stacking for Apparmor patch set in the LSM next branch for 6.1. The audit changes have polished up nicely and I believe that all comments on the integrity code have been addressed. The interface_lsm mechanism has been beaten to a frothy peak. There are serious binder changes, but I think they address issues beyond the needs of stacking. Changes outside these areas are pretty well limited to LSM interface improvements.
