Sasha has already queued the original commit and the dependencies for the 6.1, 6.0, and 5.15 stable kernels. Those kernels all had the call_lsm_notifier() to call_blocking_lsm_notifier() change. Prior to 5.3, the change to the blocking notifier would need to be backported as well. This version of the backport still needs to be reviewed. thanks, Mimi > > But also, why are you still on 4.19.y?
