-	  This option switches the layout of sysfs to the deprecated
-	  version. Do not use it on recent distributions.
-
-	  The current sysfs layout features a unified device tree at
-	  /sys/devices/, which is able to express a hierarchy between
-	  class devices. If the deprecated option is set to Y, the
-	  unified device tree is split into a bus device tree at
-	  /sys/devices/ and several individual class device trees at
-	  /sys/class/. The class and bus devices will be connected by
-	  "<subsystem>:<name>" and the "device" links. The "block"
-	  class devices, will not show up in /sys/class/block/. Some
-	  subsystems will suppress the creation of some devices which
-	  depend on the unified device tree.
-
-	  This option is not a pure compatibility option that can
-	  be safely enabled on newer distributions. It will change the
-	  layout of sysfs to the non-extensible deprecated version,
-	  and disable some features, which can not be exported without
-	  confusing older userspace tools. Since 2007/2008 all major
-	  distributions do not enable this option, and ship no tools which
-	  depend on the deprecated layout or this option.
-
-	  If you are using a new kernel on an older distribution, or use
-	  older userspace tools, you might need to say Y here. Do not say Y,
-	  if the original kernel, that came with your distribution, has
-	  this option set to N.
+	help
+	  This option adds code that switches the layout of the "block" class
+	  devices, to not show up in /sys/class/block/, but only in
+	  /sys/block/.
+
+	  This switch is only active when the sysfs.deprecated=1 boot option is
+	  passed or the SYSFS_DEPRECATED_V2 option is set.
+
+	  This option allows new kernels to run on old distributions and tools,
+	  which might get confused by /sys/class/block/. Since 2007/2008 all
+	  major distributions and tools handle this just fine.
+
+	  Recent distributions and userspace tools after 2009/2010 depend on
+	  the existence of /sys/class/block/, and will not work with this
+	  option enabled.
+
+	  Only if you are using a new kernel on an old distribution, you might
+	  need to say Y here.
