Can anyone reply a simple question? Can I return STATUS_PENDING from
IRP_MJ_CREATE?

Why not?
Of course, you can - if handled properly.

Sure, but the I/O manager will then immediately perform a
KeWaitForSingleObject on pIrp->UserEvent as soon as you return, so the
originating user thread will be blocked until you actually complete the
request. The I/O manager will do this for any user requests it considers
‘inherently synchronous’ - see p.659 of Nagar.

I do not care about that. Returning STATUS_PENDING from IRP_MJ_CREATE fits
into my driver architecture. That’s it. I know that file creation is always
synchronous.
