The point was that kernel debuggers have an at least as legitimate need as kdump to run early on panic as kdump. In particularly they should run before kdump because kdump can be triggered from the debugger.
But for modular kernel debuggers the hook would need to be exported, so in theory everyone could use it. In theory code review should catch that. Another alternative would be to readd the old namespaces patches I posted some time ago, this allowed to export symbols only to specific modules (but that would be also unfortunate for out of tree debuggers)
Since we have nearly all other needed hooks for kernel debuggers anyways it doesn't really make sense to stop at panic. So this earlier requirements should be relaxed.
Perhaps code review can solve the problem?
