Thanks for your comments. I had a look at the vmlinux.lds.h file and
there are indeed better options like DEV_KEEP etc.

Anyway, I think I'll drop this patch completely. All that kmemleak needs
is actually the kernel symbols to be able to print the stack trace.
These don't seem to be removed together with the .init sections cleanup.
