Put another way: we lived without DEBUG_RODATA for fifteen years, why
should we now start adding complexity to work around code that doesn't
accept the (fairly small) debugging it gives?
Has anybody actually found a bug using it?
As far as I know, the biggest reason to use DEBUG_RODATA is
(a) Hey, it's a cheap way to check one thing
(b) An added layer of security (which it's not that great for, but it
might make sense to make it more of a real security feature).
and neither of them really seems to say "let's add more code to other
pieces of the kernel to work around it" to me.
