Historically, the inline keyword was a strong suggestion to the compiler that it should inline the function marked inline. As compilers became better at optimising, this functionality has receded, and using inline as a suggestion to inline a function is obsolete. The compiler will happily ignore it and inline something else entirely if it finds that's a better optimisation. Therefore, remove all the occurences of the inline keyword with static functions inside single compilation unit and leave the decision whether to inline a function or not entirely on the compiler NOTE: We keep the usage the inline keyword when the purpose is to change the linkage behaviour.
