WdfSpinlock rule (kmdf)
The WdfSpinlock rule specifies that calls to the WdfSpinLockAcquire method are used in strict alternation with WdfSpinlockRelease. At the end of any KMDF callback routine, the driver should not hold the framework spinlock object that was obtained by a previous call to WdfSpinLockAcquire.
How to test
|At compile time|
Run Static Driver Verifier and specify the WdfSpinlock rule.Use the following steps to run an analysis of your code:
