To be honest, I do not even know what can I say, except that I disagree with this change. The very idea looks wrong to me. Granted, SIGKILL can kill the process which does something useful. Say, dumps a core. So what? Where does this SIGKILL come from? How often does this happen? And why do you think the core dumping is special? Say, you try to debug the buggy application, but a sudden SIGKILL kills the debuggee and you lose the debugging session. Does this mean that the kernel needs another patch to protect the process running under gdb from SIGKILL? I don't think so. Please feel free to resend this patch, but it needs a very convincing changelog. And please send it to lkml. Oleg.
