-Subject: driver core: remove CONFIG_SYSFS_DEPRECATED and
- CONFIG_SYSFS_DEPRECATED_V2
-
-From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
-
-[ Upstream commit 721da5cee9d43901105f5b8bd33fcb9101b12fc3 ]
-
-CONFIG_SYSFS_DEPRECATED was added in commit 88a22c985e35
-("CONFIG_SYSFS_DEPRECATED") in 2006 to allow systems with older versions
-of some tools (i.e. Fedora 3's version of udev) to boot properly. Four
-years later, in 2010, the option was attempted to be removed as most of
-userspace should have been fixed up properly by then, but some kernel
-developers clung to those old systems and refused to update, so we added
-CONFIG_SYSFS_DEPRECATED_V2 in commit e52eec13cd6b ("SYSFS: Allow boot
-time switching between deprecated and modern sysfs layout") to allow
-them to continue to boot properly, and we allowed a boot time parameter
-to be used to switch back to the old format if needed.
-
-Over time, the logic that was covered under these config options was
-slowly removed from individual driver subsystems successfully, removed,
-and the only thing that is now left in the kernel are some changes in
-the block layer's representation in sysfs where real directories are
-used instead of symlinks like normal.
-
-Because the original changes were done to userspace tools in 2006, and
-all distros that use those tools are long end-of-life, and older
-non-udev-based systems do not care about the block layer's sysfs
-representation, it is time to finally remove this old logic and the
-config entries from the kernel.

--config SYSFS_DEPRECATED
-- bool "Enable deprecated sysfs features to support old userspace tools"
-- depends on SYSFS
-- default 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.

--config SYSFS_DEPRECATED_V2

-- help
-- Enable deprecated sysfs by default.
--
-- See the CONFIG_SYSFS_DEPRECATED option for more details about this
-- option.
--
-- Only if you are using a new kernel on an old distribution, you might
-- need to say Y here. Even then, odds are you would not need it
-- enabled, you can always pass the boot option if absolutely necessary.
