We only employ a single task for log capture, and created a workqueue for the purpose of ensuring we had a high priority queue for low latency. We can simply use the system_highpri_wq and avoid the complication with creating our own admist the maze of mutexes. (Currently we create the wq early before we even know we need it in order to avoid trying to create it on demand while we hold the logging mutex.)
