// Overview:

// Test the KTRACE macros and debug mask related functions.

// API Information:

// UserSvr::DebugMask(), User::SetDebugMask, KDebugMask(), KDebugNum()

// Details:	

// Set debug masks and verify they are as expected. Test using 

// UserSvr::DebugMask() & User::SetDebugMask().

// In a kernel level LDD, test the kernel functions using 

// KDebugMask() & KDebugNum().
