+/*
+ * Camera HAL "CallbackWorkerThread" workaround description
+ *
+ * The camera HAL of the Exynos7580 (A3, A5, ... 2016) reguralry deadlocks when using
+ * most camera apps, this happens a lot when using Google Camera but does occur
+ * occasionally in Snap.
+ *
+ * The issue was tracked down to the way that Samsung operates their HAL, all operations
+ * are run in multiple threads and the different callbacks are executed from one of these
+ * threads.
+ *
+ * The deadlocks occur when the camera client executes a function like cancel_auto_focus
+ * or stop_preview and a callback from the HAL occurs at around the same time. The HAL
+ * waits for the callback functions to return before they finish processing the client
+ * calls and the client stops processing callbacks until their calling function completes.
+ *
+ * You end up in a state when both the HAL and the client are waiting for the other
+ * process to finish and so end up with a deadlock of the HAL/Client which only a reboot
+ * can cure.
+ *
+ * This worker thread offloads the actual callbacks to another thread which allows the
+ * HAL to finish the client calls and avoid the deadlock scenario.
