I'm searching for a position in our kernel mode code, which
compares a variable with STATUS_UNSUCCESSFUL. That does mean,
there is somewhere a '==' followed by 'STATUS_UNSUCCESSFUL'
or 'STATUS_UNSUCCESSFUL' followed by '=='.
io/pnpmgr.c function IopTraverseDeviceTree (line 736) is the only one I
could find in ntoskrnl.
