What is the reason for all the noinlines in this file?

Something to do with getting proper wchan output? I guess it doesn't hurt
from a documentation POV, but did you find that it was actually necessary?

IOW: is gcc now capable of secretly inlining functions which are defined
further ahead in the compilation unit?


(did you actually "test" the wchan stuff, btw?)
