The point is that the behaviour before the relatime patch was that
the kernel updated the atime to the current time as the kernel
knows about it, it didn't make any decision about "the past" or
"the future".

Relatime is about reducing the frequency of atime updates, not
about deciding that one timestamp is more correct than another. 

That makes sense.

Indeed, that's what the commit message should say rather than
drawing arbitrary lines in the sand about what is a valid atime
without further justification.

Cheers,

Dave.
