Hi,
I've been using scanner.sys as an example of a file filter.
When going over the code, I found a call to
RtlCompareUnicodeString - which according to the documentation can be
called at IRQL = PASSIVE_LEVE.
In the sample it is call from a function that can be called in other
IRQLs.

Is it a bug or - can I keep this call?

Thanks,
Tam

The only place where I see it used is from the post create callback which is
called at PASSIVE_LEVEL.
