Using StorPortFreePool in ScsiStopAdapter

NTDEV

Hi,

In the Microsoft AHCI Storport Miniport Driver, StorPortFreePool function has been used in ScsiStopAdapter which runs at DIRQL. But as per the MSDN docs, the StorPortFreePool should be used in functions running at <= DISPATCH LEVEL.

Can we use StorPortFreePool in ScsiStopAdapter? Will there not be in any DVL violations?

The Microsoft AHCI Storport Miniport Driver was downloaded from the below link.

ScsiStopAdapter is called for both power down and PnP remove. For power down
you’re called at DIRQL, but in the case of PnP remove you are called at IRQL
PASSIVE_LEVEL.
