They have a similar purpose, but they do not work the same way at all.

My patch (comment #2) politely asks the kernel not to update the atime of
opened files. It only works if the O_NOATIME flags exists on that particular
platform but has no other drawbacks.

AFAIK, the patch on rsync-patches.git explicitly puts back the atime to what it
was. It has the drawback of updating the ctime instead.
