+commit e694958388c50148389b0e9b9e9e8945cf0f1b98

+
+    Make sock_sendpage() use kernel_sendpage()
+    
+    kernel_sendpage() does the proper default case handling for when the
+    socket doesn't have a native sendpage implementation.
+    
+    Now, arguably this might be something that we could instead solve by
+    just specifying that all protocols should do it themselves at the
+    protocol level, but we really only care about the common protocols.
+    Does anybody really care about sendpage on something like Appletalk? Not
+    likely.
