Subject: couldn't seal address 0 ret=-12 running kernel 6.13 an setarch

Hello:

Running setarch -Z now results in the following log entry

pid=200610, couldn't seal address 0, ret=-12.

There is nothing this process can do if the kernel is failing to seal
the address, the message will also be much better if it had a process
name together with the pid.

Im anot not sure if this hides a bug somewhere or it is just an
annoying message and ergo Im posting it here.
