+Subject: [PATCH] mountd: Add check for 'struct file_handle'
+
+The code to check if name_to_handle_at() is implemented generates only a
+warning but with some toolchain it doesn't fail to link (the function must be
+implemented somewhere).
+However the "struct file_handle" type is not available.
+
+So, this patch adds a check for this struct.
