Unfortunately my 4.4 test fails quickly:
./include/linux/jiffies.h: In function ‘jiffies_delta_to_clock_t’:
./include/linux/jiffies.h:444: error: first argument to
‘__builtin_choose_expr’ not a constant
static inline clock_t jiffies_delta_to_clock_t(long delta)
{
return jiffies_to_clock_t(max(0L, delta));
}
I think this is the same problem of using __builtin_constant_p() in
4.4 that we hit earlier? :(
