I figure 2-3 days.
Okay. I think we need to submit a revert for v5.8 and -stable (which
is pretty limited at this point); can you put that together and send
it to the list? It should be trivial, if you can't do it let me know.
I'm trying to remember the name of the tool to build a function
calling
tree, either up or down. Was it cscope? Or is there something more
modern? It will have some limitations due to op function pointers.
I'm not sure what you're talking about, I always just walk the code by
hand in my editor with cscope or lxr as tools on the side.
