WdfWaitlockRelease rule (kmdf)

The WdfWaitlockRelease rule specifies that calls to WdfWaitLockAcquire and WdfWaitLockRelease are used in a balanced way within a KMDF event callback function. When the KMDF event callback function returns, the driver should not hold the framework spin lock object that was obtained by a previous call to WdfWaitLockAcquire.

Driver model: KMDF

How to test

At compile time

Run Static Driver Verifier and specify the WdfWaitlockRelease rule.

Use the following steps to run an analysis of your code:
  1. Prepare your code (use role type declarations).
  2. Run Static Driver Verifier.
  3. View and analyze the results.
