No, I'm afraid I don't have one that I know cannot possibly be expressed by reference to a function symbol only. I'd look at systemtap (4.3) probe point lists like: % stap -vL 'kernel.statement("*@kernel/*verif*.c:*")' % stap -vL 'module("amdgpu").statement("*@*execution*.c:*")' which give an impression of computed PC addresses. > It seems like something like that would reference the enclosing > section, which means we can't just leave them out of the sysfs > list...
