Hi,
From the book 'Linux Device Drivers' by Alessandro Rubini :
"... The best approach to prevent namespace pollution is to declare
all your symbols as static and to use a well-defined prefix for the
symbols you leave as global."
By namespace pollution, the author is referring to the problem
which occurs when device driver writers may create functions / global
variables that maybe used elsewhere in the kernel.
My question is this : how does using 'static' variables solve this
problem? I was not aware that static variables / function pointers had
such a property.
