Ok, here's what I have. I note again that my usage of coccinelle is
pretty primitive, so I ended up doing a fair bit of by-hand fixing after
applying these.

Given the way that this change is broken up into 77 patches by
subsystem, to which changelogs should I add it? I could add it to the
"infrastructure" patch, but that's the one where I _didn't_ use it. 

Maybe to patch #79 (the one that renames i_ctime)?
