KsProcessingMutex rule ()

The KsProcessingMutex rule specifies that a KS miniport driver uses the processing mutex in the correct sequence:

• The processing mutex cannot be obtained recursively.
• A thread that has acquired the processing mutex should not subsequently attempt to acquire the filter control mutex.
• A thread should not release the processing mutex without acquiring it first.

Driver model: KS

Bug check(s) found with this rule: Bug Check 0xC4: DRIVER_VERIFIER_DETECTED_VIOLATION (0x0008100B)

How to test
