sl@0: // Overview:
sl@0: // Test application that uses the reference defragmantation driver to invoke
sl@0: // the top-level defragmentation operations.
sl@0: // API Information:
sl@0: // RBusLogicalChannel
sl@0: // Details:
sl@0: // - Load and open the logical device driver ("D_DEFRAG_REF.LDD"). Verify
sl@0: // results.
sl@0: // - Request that the driver attempt to trigger various defragmentation
sl@0: // operations. Verify that they complete successfully.
sl@0: // Platforms/Drives/Compatibility:
sl@0: // Hardware only. No defrag support on emulator.
sl@0: // Assumptions/Requirement/Pre-requisites:
sl@0: // Failures and causes:
sl@0: // Base Port information:
sl@0: //
