Hi Thomas, Thank you for the review. I will reword the patch comment. Currently, at the end it says: "Thus, make notsc to behave the same as tsc=unstable." To emphasize this, I will change the patch title to this: x86/tsc: redefine notsc to behave as tsc=unstable And in the comment I will mention that as a consequence of this change tsc is going to be used by sched_clock() when notsc is provided. Thank you, Pavel
