Hello Johannes Berg, The patch a06ae2017b9e: "kernel.h: hide __is_constexpr() from sparse" from Nov 17, 2018, leads to a bunch of Smatch warnings. We stubbed out __is_constexpr() to return always true because Sparse was complaining but Smatch needs the __is_constexpr() to work or it can't parse min()/max() macros. regards, dan carpenter
