One other possibility is to keep atime updates in memory and only write them out to disk if the page was to be flushed to disk anyway. That would mean storing atimes in memory in a separate structure outside of the regular page.

The additional memory requirements should be relatively small, but the extra time needed to perform atime lookup might not be.

It would also mean that after a crash atimes will be wrong.
