This patch series attempts to implement basic support for Ultrajoiner functionality. Rev6: -Upgrade the debugfs functionality to enable the joining of a specified number of pipes. -Modify the display helpers reliant on the pipe joiner mechanism to use number of pipes joined, instead of joiner flag. -Checkpatch fixes.
