    16 // Test nanokernel implicit system lock
       
    17 // API Information:
       
    18 // NKern::LockSystem and NKern::UnlockSystem
       
    19 // Details:
       
    20 // - Load and open the logical device driver ("D_IMPLICIT"). Verify results.
       
    21 // - The LDD uses three separate threads to test the nanokernel implicit 
       
    22 // system lock with changing priorities, round-robin and a "dry run".
       
    23 // - Close the channels and verify results are as expected.
       
    24 // Platforms/Drives/Compatibility:
       
    25 // All.
