This is *exactly* what the statcache does. After this cache
is built, and a pathname comes in then a lookup is done to
match the longest name in the cache, then the stat is done
to ensure the mapping is still valid.

You pick the first one that matches, what else can you do ?

This is what the statcache *does* :-) :-). The stat is
done at the end of the lookup to determine if the mapping
is still valid.

Am I not being clear enough ? Is the code not clear here ?
