);
Parameters
[in] HwDeviceExtension
Pointer to the miniport's hardware device extension.
[in/optional] ThreadContext
Pointer to the thread context received in a prior call to StorPortCreateSystemThread.
[in] PreviousAffinity
Pointer to a STOR_GROUP_AFFINITY structure with the group affinity to restore. This group affinity was obtained in a prior call to StorPortSetSystemGroupAffinityThread.
Return value
StorPortRevertToUserGroupAffinityThread returns one of the following values:
| Return code | Description |
|---|---|
| STOR_STATUS_SUCCESS | The original group affinity was restored successfully. |
| STOR_STATUS_INVALID_IRQL | IRQL level must be <= DISPATCH_LEVEL. |
| STOR_STATUS_INVALID_PARAMETER | One or more of the provided parameters are invalid. |
| STOR_STATUS_UNSUCCESSFUL | Returned for other internal system reasons. |

If a miniport calls StorPortSetSystemGroupAffinityThread to temporarily change the group affinity of the thread, then it should call StorPortRevertToUserGroupAffinityThread to revert thread affinity to its original value before the thread exits.
