+KernelVersion:	2.6.22
+Contact:	Artem Bityutskiy <[email protected]>
+Description:
+		The ubi/ class sub-directory belongs to the UBI subsystem and
+		provides general UBI information, per-UBI device information
+		and per-UBI volume information.
+
+What:		/sys/class/ubi/version
+Date:		July 2006
+KernelVersion:	2.6.22
+Contact:	Artem Bityutskiy <[email protected]>
+Description:
+		This file contains version of the latest supported UBI on-media
+		format. Currently it is 1, and there is no plan to change this.
+		However, if in the future UBI needs on-flash format changes
+		which cannot be done in a compatible manner, a new format
+		version will be added. So this is a mechanism for possible
+		future backward-compatible (but forward-incompatible)
+		improvements.

+		device information and per UBI volume information (each UBI
+		device may have many UBI volumes)

+		this volume has to be aligned on. For example, 2048 means that
+		logical eraseblock size is multiple of 2048. In other words,
+		volume logical eraseblock size is UBI device logical eraseblock

+Contact:	Artem Bityutskiy <[email protected]>
+Description:
+		Contains ASCII "0\n" if the update marker is not set for this
+		volume, and "1\n" if it is set. The update marker is set when
+		volume update starts, and cleaned when it ends. So the presence
+		of the update marker indicates that the volume is being updated
+		at the moment of the update was interrupted. The later may be
+		checked using the "corrupted" sysfs file.
+
+What:		/sys/class/ubi/ubiX/ubiX_Y/usable_eb_size
+Date:		July 2006
+KernelVersion:	2.6.22
+Contact:	Artem Bityutskiy <[email protected]>
+Description:
+		Logical eraseblock size of this volume. Equivalent to logical
+		eraseblock size of the device aligned on the volume alignment
+		value.

+Contact:	Peter Zijlstra <[email protected]>
+Description:
+
+Provide a place in sysfs for the backing_dev_info object.  This allows
+setting and retrieving various BDI specific variables.
+
+The <bdi> identifier can be either of the following:
+
+MAJOR:MINOR
+
+	Device number for block devices, or value of st_dev on
+	non-block filesystems which provide their own BDI, such as NFS
+	and FUSE.
+
+default
+
+	The default backing dev, used for non-block device backed
+	filesystems which do not provide their own BDI.
+
+Files under /sys/class/bdi/<bdi>/
+---------------------------------
+
+read_ahead_kb (read-write)
+
+	Size of the read-ahead window in kilobytes
+
+min_ratio (read-write)
+
+	Under normal circumstances each device is given a part of the
+	total write-back cache that relates to its current average
+	writeout speed in relation to the other devices.
+
+	The 'min_ratio' parameter allows assigning a minimum
+	percentage of the write-back cache to a particular device.
+	For example, this is useful for providing a minimum QoS.
+
+max_ratio (read-write)
+
+	Allows limiting a particular device to use not more than the
+	given percentage of the write-back cache.  This is useful in
+	situations where we want to avoid one device taking all or
+	most of the write-back cache.  For example in case of an NFS
+	mount that is prone to get stuck, or a FUSE mount which cannot
+	be trusted to play fair.
