Yes, I tested linux-next everyday and saw enough of those cleanup efforts ends up introducing regressions. It is almost every day or two I had to investigate at least one regression and pick the suckers out even though my testing is only focus on MM and friends. However, I do agree if there are worthy cleanup and refactoring but those tiny ones make me uncomfortable. See, I am just trying to save a real vacation for a few weeks in the future, but given the current situation, Iâll need to give up on this project [1] at all because I just have no courage to debug all the regressions there once back.
