Details:


I've discovered that find is causing pagecache poisoning on systems with
large filesystems (millions of files).

This can probably be mitigated by using fadvise() to tell the OS that
files/directory data doesn't need to be cached.

As far as I can tell it isn't used in any release version of find.

Can the devs look at incorporating this please?
