IoDeleteDevice from FS Notification

NTFSD
1

In a fsf driver is it okay to call IoDeleteDevice from FS Notification
routine.

2

It is OK from FastIoDetachDevice.

FastIoDetachDevice.

Thnx Maxim for your reply.Another question for you:
Fs filter create dev obj and attach to FS control dev obj in FS notification
(IoRegFilesys).
so must it not delete the object in FS notification during
(IoUnRegFilesys)…

Can anyone else confirm this? Has anyone else been deleting the device
objects in
FS notification. I guess many of the fs filters must have been based on
sfilter.
