Miniport drivers are required to acquire the MSI spin lock for a message if, and only if, the InterruptSynchronizationMode member of the PORT_CONFIGURATION_INFORMATION (Storport) structure is set to InterruptSynchronizePerMessage. This rule verifies that calls to StorPortAcquireMSISpinLock are only made if the synchronization mode is InterruptSynchronizePerMessage.
Driver model: Storport
