So if someone accidentally changes time back a few days, access
times go backwards for everything? That doesn't sound right to me -
it's going to seriously screw up backups and other scanners that use
atime to determine "newly accessed files"....
IMO, if you fat-finger a manual atime update or use atimes direct
from tarballs, then that's your problem as a user and not the
responsibility of the kernel to magically fix for you....
