+    cls/rbd, librbd: use uint64_t for sparse_size
+    
+    the size of `size_t` is varies from architecture to architecture. the
+    C++ standard only requires it to be able to represent the maximum possible
+    size of object of any type. on 32-bit architectures, it's very likely a
+    32-bit unsigned integer. to ensure the interoperability between the
+    64-bit systems and 32-bit systems, we should use a type with explicitly
+    defined size.
+    
+    also, we don't define the dencoder for size_t. so on systems where
+    size_t is not backed by uint32_t or uint64_t, the tree does not compile.
+    
+    in this change, use uint64_t for sparse_size. and leave
+    `C_SparsifyObject::m_sparse_size` intact. as the latter should be able
+    to be promoted to uint64_t when necessary.
+    
+    this change is backward compatible on 64-bit systems.
+
