Well, actually this was my original plan, but Linus asked for the treewide script to be done in this -rc release, and that part was only done on his request. https://lore.kernel.org/all/CAHk-=whKE5UL+AuCC2wK8oq8D_ueSO_T7-9Acx4POouqVi8ZHg@mail.gmail.com/ > > How long have you been around doing kernel development and how much fuzz > do you make about even trivial changes to ftrace? This is my first "treewide" change I'm doing, so I'm going to make mistakes. Hence why I started this all off with RFC. I'll rebase this on next and break this patch up into more comprehensible bits. -- Steve
