By the way, there is another somewhat related issue that needs to be
addressed. 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:
