I don't think I dropped this. Which one are you thinking?

Yes, this was deliberate. For plain read/write it's simply
unnecessary, since it should get 100% hit rate on the c/mtime tests.
For mmap we do need something, and that something might be best done
by looking at backing inode times. But even in that case I'd just
compare the times from a previous version of the backing inode to the
current version, instead of comparing with the cached values.
