Actually everything should be included. Smatch has cross-function db and
I am using it for getting the call chains and it follows function pointers.
Also since I am starting from a list of individual read IOs, every single
base read IO in drivers/* should be covered as far as I can see. But if it uses
some weird IO wrappers then the actual list might be higher.
