   \frametitle{Different SLAB Allocators}
+  There are three different, but API compatible, implementations of
+  a SLAB allocator in the Linux kernel. A particular implementation
+  is chosen at configuration time.

-  \item There are three different, but API compatible, implementations of
-    a SLAB allocator in the Linux kernel. A particular implementation
-    is chosen at configuration time.
-    \begin{itemize}
-    \item SLAB: legacy, well proven allocator.\\
-          Still the default in most ARM \code{defconfig} files.
-    \item SLOB: much simpler. More space efficient but doesn't scale
-      well. Saves a few hundreds of KB in small systems (depends on
-      \code{CONFIG_EXPERT}) \\
-      Linux 4.4 on ARM: used in 5 \code{defconfig} files
-    \item SLUB: more recent and simpler than
-      SLAB, scaling much better (in particular for huge systems) and
-      creating less fragmentation.\\
-      Linux 4.4 on ARM: used in 0 \code{defconfig} files
