The purpose of 'SingleDisk' is the same as in the IopCreateArcNames() function. It is an optimization for that when looking up the firmware-recognized ARC disks list, in order to match one of these with the current NT disk being analysed (see e.g. also in IopCreateArcNamesDisk()), we avoid a possible IopVerifyDiskSignature() call and directly build a corresponding ARC name NT symbolic link for it. 'SingleDisk' will actually be TRUE, whether the DiskSignatureListHead list is empty or contains only one element: Indeed in only both these cases, 'DiskSignatureListHead.Flink->Flink' will refer to the list head. (If the list is empty but 'SingleDisk' is TRUE, this does not matter, because the DiskSignatureListHead looking-up loop never starts.) |
