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.
