SpinLock rule (storport)
This rule verifies that a call to KeAcquireSpinLock is promptly followed by a call to KeReleaseSpinlock. If a driver calls KeAcquireSpinLockRaiseToDpc or KeAcquireSpinLock again prior to releasing the lock, it fails the rule. In addition, before exiting the dispatch or cancel routine, the driver must release the spin lock.
How to test
|At compile time|
Run Static Driver Verifier and specify the SpinLock rule.Use the following steps to run an analysis of your code:
