Li Wang 88285f766c ceph: Avoid data inconsistency due to d-cache aliasing in readpage()
commit 56f91aad69 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.
