If atime has been wrong set to future, then it cannot
be updated back to current time.

+#define RELATIME_MARGIN (24 * 60 * 60)

Nice patch overall.  Should this be a #define, or a CONFIG_ variable,
or a tweakable /proc/sys/fs variable?  Or am I senile and we thrashed
all this out once before when the relatime code landed?

I recall the consensus was that a /proc tunable was "too much" for the
initial patch.

OK, in that case yangsheng's patch is probably good to go.
