When my redirector can’t process the modified page writer’s async write
request without blocking(maybe some resource can’t be acquied), what
status should be returned to the modified page writer? Is STATUS_RETRY ok?
Thanks in advance.

If you can’t process async request without blocking you need to mark IRP
pending, return STATUS_PENDING and process it in another thread.

But NT File System Internal said that the modified page writer’s requests
should not be post to other thread. Can I just reject the request with an
error status? I think the modified page writer will try to write out other
pages.
