 	  This core has a bunch of cool new features:
 	  -MMU-v3: Variable Page Sz (4k, 8k, 16k), bigger J-TLB (128x4)
-                   Shared Address Spaces (for sharing TLB entires in MMU)

+ *
+ * The VFS allows partial EOF blocks to "match" for dedupe even though it hasn't

+ * EOF block in the source dedupe range because it's not a complete block match,
+ * hence can introduce a corruption into the file that has it's block replaced.

+ * In similar fashion, the VFS file cloning also allows partial EOF blocks to be

+ * source file range includes the EOF block and it lands within the existing EOF
+ * of the destination file, then we can expose stale data from beyond the source
+ * file EOF in the destination file.
+ *
+ * XFS doesn't support partial block sharing, so in both cases we have check
+ * these cases ourselves. For dedupe, we can simply round the length to dedupe
+ * down to the previous whole block and ignore the partial EOF block. While this
+ * means we can't dedupe the last block of a file, this is an acceptible
+ * tradeoff for simplicity on implementation.
+ *
+ * For cloning, we want to share the partial EOF block if it is also the new EOF
+ * block of the destination file. If the partial EOF block lies inside the
+ * existing destination EOF, then we have to abort the clone to avoid exposing
+ * stale data in the destination file. Hence we reject these clone attempts with
