Note that this requires 2 things:
1) A kernel built with CONFIG_DEBUG_RODATA=y
2) The structure needs to have a compile-time initializer:
struct foo barbaz = { 5, 3, "quuz"};
Otherwise, your kernel will throw an oops when it tries to initialize
the structure at runtime (which is almost certainly *not* the time that
is causing the actual problem).
Simply declaring it as 'const struct' may or may not help - this will catch
at compile time lots of mistakes, but isn't guaranteed to stop all cases of
buggy uses of miscast pointers, etc....
