-- cache by filename key is correct and good for most cases and should
be on by default
-- the grace period is a clever solution for the

Can I ask why the filename is important for the cache key? With the
cache delay, the inode/dev + *time + size should do it all.
In fact, I finally understood the difference between mtime and ctime, if
any change is made, it should be the change to ctime.
Why ctime? ctime is unique in that
