The kernel has used:
# define inline inline __attribute__((always_inline))

For a looong time.

So anyone in the kernel when they said "inline" actually
said to gcc: if you have any possible way to do so inline this
sucker.

Now we have a config option that changes this so inline is only
a hint. gcc does not pay enough attention to the hint,
especially compared to the days where the hint was actually a command.
