-         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 switches the layout of the "block" class devices, to not
+         show up in /sys/class/block/, but only in /sys/block/.
+
+         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. Never say Y, if the original kernel, that came
+         with your distribution, has not set this option.
