For obvious reasons we can not only take this patch (from 6.2-rc1) into 4.19.y as that would cause people who upgrade from 4.19.y to a newer stable kernel to have a regression.
Please submit backports for all stable kernels if you wish to see this in older ones to prevent problems like this from happening.
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? What is wrong with 5.4.y at this point in time? If we dropped support for 4.19.y in January, what would that cause to happen for your systems?
