I believe kernel needs to free user space from this trick found even in kernel sources themselves: tools/testing/selftests/ptp/testptp.c:87: static clockid_t get_clockid(int fd) { #define CLOCKFD 3 return (((unsigned int) ~fd) << 3) | CLOCKFD; } Once upon a time there was a patch for that, but I don't think it addressed the issue correctly, here is more background: https://lore.kernel.org/lkml/87y2pxvsbr.fsf@xxxxxxxxxxx/ Thanks, -- Sergey
