Alex Ionescu 6555616bb6 - Uber-optimize IopQueryAttributesFile by using the OPEN_PACKET mechanism to query file attributes, instead of doing lots of slow native calls.
- Modify IopParseDevice to detect when OPEN_PACKET optimizations are in use (query or deletion (deletion not yet implemented)) and have some codepaths be slightly different and use DUMMY_FILE_OBJECT.
- Implement QueryOnly case in IopParseDevice to handle attribute queries.
- Add a missing dereference, and remove an extra DO reference.
