I suspect none of these "Heads" spend much time in protracted email debug sessions. Because the *first* thing you do is ask the tester to compile the relevant driver into the kernel.
The problems which the removal of this option will cause include:
1: Inability to look up symbols in the kernel elf image. 2: Breaks the kernel profiler 3: breaks kgdb 4: breaks ksymoops.
How often have we seen nonsensical backtraces here because modules were involved? Possibly we can include a table of module base addresses in the Oops output and teach ksymoops about it.
This proposal is, frankly, brain-damaged. It will significantly impeded kernel developers in remote problem diagnosis and it will weaken the kernel development toolchain.
There's a lot of work to be done to overcome this damage, and given the difficulty of getting debug tools into the mainstream kernel, the damage may well be permanent.
