So the bugzilla entry worries me a bit - we definitely do not want to
regress in case somebody really relied on timing - but without more
specific information I still think the real bug is just in the
man-page.
Side note: the 2MB limit may be too small. 2M is peanuts on modern
machines, even for fairly slow IO, and there are lots of files (like
glibc etc) that people might want to read-ahead during boot. We
already do bigger read-ahead if people just do "read()" system calls.
So I could certainly imagine that we should increase it.
I do *not* think we should bow down to insane man-pages that have
always been wrong, though, and I don't think we should increase it to
"let's just read-ahead a whole ISO image" kind of sizes..
Okay, how about something like 256MB? I would be happy to send a patch
for that change.
