From: Andy Adamson <andros@xxxxxxxxxx>
The layoutdriver_io_operation initalize_mountpoint is used to set up the
generic device id cache.
The super block and file handle parameters are unused except by the block
layout driver which uses them to call GETDEVICELIST.
A getdevicelist call will be added for the block layout driver.
