Been there done that.. we have too much self modifying code for that not to have been needed. Use gdb on /proc/kcore and disassemble self to see the _real_ code. But yes, tricky stuff. Not arguing we need relocations in alternatives, just saying debugging them (and static keys and others) is great fun.
