[PATCH RFC] do_settime is backwards?!
While digging through the time code, I found something very strange
in do_settime:
x = (secs * 1000000000ULL) + (u64)nsecs - system_time_base;
y = do_div(x, 1000000000);
spin_lock(&wc_lock);
wc_sec = _wc_sec = (u32)x;
wc_nsec = _wc_nsec = (u32)y;
spin_unlock(&wc_lock);
The value "x" appears to be the number of nanoseconds, while
the value "y" is the value in seconds. The assignments to...
