tmpfs' "API" and was already rotting. Instead, merge all the relevant comments into the code. This includes acknowledgements to Google's Summer of Code 2005 program (they were in the AUTHORS section of tmpfs(9) before), so all the files need to be changed to include this sentence alongside the title. (Note that this was not a requirement of the program.)
