Since Lazytime Mount applied to my kernel requires Fsync, Fsync should not be switched off. Also, Fsync Off is not very effective for real use. Hotplug-off(8 cores online) works automatically when you activate additional booster in Intelli Perfomance of Gametuner-MOD.
I will consider adding them as a separate option, but the features you requested are options for the expert. Are you keen on the kernel?
