r3595: - fixed a talloc_free ordering problem on cleanup with pending requests
- added initial support for MODE_INFORMATION in setfileinfo (I have no idea what "mode information" on a file is - it takes a value of 0, 2, 4 or 6. What could it be?) (This used to be commit e53ec2f6b68e1d19149c36ea8fcd25a204db38fb)
