I assume /dev/crash is read only
I don't know. But if that matters, why can't we make /dev/mem
write-only for certain areas and read-only for the rest ...?
You either want this at compile time or you don't want it at all.
Why? You don't write something about my arguments (as Alan does, even
though I disagree), you only write that you "nak" it.
