ceph: Avoid data inconsistency due to d-cache aliasing in readpage() commit 56f91aad69444d650237295f68c195b74d888d95 upstream. If the length of data to be read in readpage() is exactly PAGE_CACHE_SIZE, the original code does not flush d-cache for data consistency after finishing reading. This patches fixes this.
