__invalidate_device without the kill_dirty parameter just invalidates
various clean entries in caches, which doesn't really help us with
anything, but can cause all kinds of horrible lock orders due to how
it calls into the file system.  The only reason this hasn't been a
major issue is because so many people use partitions, for which no
invalidation was performed anyway.
