You can see they complain about over use of inline, especially since
gcc will find the obvious cases on its own.
This was really interesting

Yes.
So why is that used in the code timer.c?
What I understand with respect to static and inline functions is
To make a function call CPU has to save registers and pass on ret
instructions when ever the function call ends
if we have a small fucntion which is used in a file and a function
call via CPU then over head of saving flag registers
Sorry in previous post I did not made clear actually what I wanted to
say is if you have a function is used at 10 places and you declare it
inline 10 times then there would be cache miss more and then it will
have disadvantage.
