None of the functions in this file are in kernel doc format, so why do
it for just this one?  Does it get added to the kernel documentation
output when it is generated?  If not, I wouldn't worry about it at all.


Also, an atomic variable is a huge hint that maybe this function is
doing something wrong, why does this need to be an atomic at all?
