Not all services involved in block I/O go through VM to access the blocks they need. As a result, the blocks in VM may become stale, possibly causing corruption when the stale copy is restored by a service that does go through VM later on. This patch restores support for forgetting cached blocks that belong to a particular device, and makes the relevant file systems use this functionality 1) when requested by VFS through REQ_FLUSH, and 2) upon unmount.
