> the .callee stuff which is getting pulled in somehow
Because that test includes vm.*.*, and with alias suffixes that will expand
some (vm.*).* like vm.brk.* to kernel.function("do_brk").*, which then expands
.callees on it. Try stap -l vm.*.callees for more, and notice that not all of
the vm aliases get callees. That's because some have an explicit .call in them
already, which doesn't have any further suffixes possible.
AFAICT, vm.pagefault.return is the only one that actually intended to use a
3-part alias, so one solution might be to remove vm.*.* from that test and just
specify that one explicitly.
