Query Std Info in completion routine?

In a legacy file system filter driver’s IRP_MJ_WRITE completion routine,
for non paging I/O’s, is it legal to query FILE_STANDARD_INFORMATION (on
the same FO as the write is targeting) “when safe”, i.e. in the completion
routine if at PASSIVE_LEVEL, synchronized back to dispatch otherwise?

Thanks,
