"There is no buffer cache".
There's a pagecache, which caches the contents of files and block devices.
You can invalidate the block device pagecache with `blockdev --flushbufs' but
there is no interface for invalidating the pagecache of regular files.
Allocating and then freeing a ton of anonymous memory, then running a
swapoff/swapon cycle might suit.
