What? Where did you find that insane sentence? And where did you find
an application that depends on that totally insane semantics that sure
as hell was never intentional.
If this comes from some man-page, then the man-page is just full of
sh*t, and is being crazy. The whole and *only* point of readahead() is
that it does *not* block, and you can do it across multiple files.
So NAK NAK NAK. This is insane and completely wrong. And the bugzilla
is crazy too. Why would anybody think that readahead() is the same as
read()?
