The fadvise call only trashes cache that has already been written to disk.
LOL!
An what's the call to trash the cache that HASN'T been written to disk?
Well, drop_caches first causes the dirty cache pages to be written, then trashes them. One might assume that WONTNEED would also flush any dirty cache pages to disk, then trash them. The man page clearly states that is not true, if they are dirty, they are ignored.
