   \frametitle{Linux kernel size (1)}
   \begin{itemize}
-  \item Linux 4.6 sources:\\
-    Raw size: 730 MB (53,600 files, approx 21,400,000 lines)\\
-    \code{gzip} compressed tar archive: 130 MB\\
-    \code{xz} compressed tar archive: 85 MB
-  \item Minimum Linux 3.17 compiled kernel size,
-        booting on the ARM Versatile board (hard drive on PCI, ext2
-        filesystem, ELF executable support, framebuffer console and input devices):\\
-    	876 KB (compressed), 2.3 MB (raw)
+  \item Linux 4.11 sources:\\
+    \begin{itemize}
+	\item 57994 files (\code{git ls-files | wc -l})
+	\item 23144003 lines (\code{wc -l $(git ls-files)})
+	\item 675576310 bytes (\code{wc -c $(git ls-files)})

+  \item Minimum Linux 4.11 compiled kernel size,
+        booting to a shell on the ARM Versatile board:
+    	405,464 bytes (compressed), 1,112,264 bytes (raw)
   \item Why are these sources so big?\\
     Because they include thousands of device drivers, many network
     protocols, support many architectures and filesystems...
