    labs/kernel-module-simple: don't use git add -A
    
    Using 'git add -A' is a terrible thing to teach people. Tell them to
    use 'git add' explicitly on the files to be added.

-\item \code{git add -A} adds (or removes) files to the next commit

-      run \code{git add} on each of the files that you want to
-      add to the next commit.
+\item \code{git add} adds files to the next commit. It is mandatory to
+  use for new files that should be added under version control.
 \item \code{git commit -a} creates a commit with all modified files
-      (at least the ones tracked by the repository) since the previous
-      commit.

 \item \code{git commit -s} adds a \code{Signed-off-by:} line to the
       commit message. All contributions to the Linux kernel must have
       such a line.
