Description
Currently there's three infrastructures that can trace the exit of the function.
kretprobes
function_graph
BPF direct trampolines
Each one does it differently, and they can stumble over each other when they trace the same function call return. There should be a way that all three can somehow use the same infrastructure. At least maybe two of them?
There's been prototypes to do this, but nothing satisfactory as of yet. Perhaps a meeting of the minds can help make this work?
