So I'm rather busy with other stuff currently so if you can pick up my patches and finish them, it would be good. I think I have addressed all the comments you had to the previous version, except for handling the case where all the workers are too busy - maybe using a dedicated workqueue with a rescueue worker instead of system_wq would solve this issue. I've sent the current version of patches I have to you including the patch 3/3 which I use for debugging and testing whether the async printing really helps avoiding softlockups.
