+This file describes sysfs files created for each storage.

+1. Per-storage files.
+Each storage has its own dir /sysfs/devices/$storage_name,

It's always /sys/devices/.

+which contains following files:
+
+alg - contains name of the algorithm used to created given storage
+name - name of the storage
+nodes - map of the storage (list of nodes and their sizes and starts)
+remove_all_nodes - writable file which allows to remove all nodes from given
+ storage
+n-$start-$cookie - per node directory, where
+ $start - start of the given node in sectors,
+ $cookie - unique node's id used by DST
+
+2. Per-node files.
+Node's files are located in /sysfs/devices/$storage_name/n-$start-$cookie
+directory, described above.

To which class or bus do the devices you create belong? Care to show a
"tree" or "ls -la" of the device?
