New Revision: 22290
URL: http://svn.reactos.ru/svn/reactos?rev=22290&view=rev
Log:
- Add the OPEN_PACKET structure to internal headers. Used for the I/O Parse Routine.
- Gut down IopCreateFile to the strict minimum so that only the critical parts remain.
- NT Compatiblity fix in ObFindObject: stop parsing if remaining path is null, this means
that the parse routine is done parsing and that -this- is the final object.
