They both do the same - gcc is no longer forced to inline these 
functions.

With either my patch or the "optimized inlining" it's 100% gcc's 
choice whether or not to inline functions marked as "inline" in 
kernel/sched* .

If you didn't complain when "x86: add optimized inlining" got into 
Linus' tree you can't validly complain about my patch.
