By collecting the head of the linked list of background tasks, this will not happen. One hypothetical case where this could happen is if an MP3Decoder is deleted while its callback to fill its buffer is scheduled. supervisor: usb: note that it's unusual to need to call usb_background 2020-07-15T16:49:44+00:00 Jeff Epler jepler@gmail.com 2020-07-14T15:08:07+00:00 urn:sha1:81105cb9ef68c4d88eab206f111af448440c8f30 supervisor: factor supervisor_background_tasks from sundry ports 2020-07-15T16:49:44+00:00 Jeff Epler jepler@gmail.com 2020-07-13T15:33:58+00:00 urn:sha1:1df48176ce2e4111c4629269cb86d2a6e365a3d2 supervisor: factor out, Handle USB via background callback 2020-07-15T16:49:44+00:00 Jeff Epler jepler@gmail.com 2020-07-07T16:14:43+00:00 urn:sha1:6160d11c5a04f60e54ce977fd73fafa5ba858aa0 background_callback: Avoid CALLBACK_CRITICAL_BEGIN with nothing to do 2020-07-15T14:26:47+00:00 Jeff Epler jepler@gmail.com 2020-07-10T19:42:21+00:00 urn:sha1:36b46465167f15eaf8535608b16859e6de10fac8 CALLBACK_CRITICAL_BEGIN is heavyweight, but we can be confident we do not have work to do as long as callback_head is NULL. This gives back performance on nRF. supervisor: tick: only run background tasks once per tick 2020-07-15T14:26:47+00:00 Jeff Epler jepler@gmail.com 2020-07-09T14:47:10+00:00 urn:sha1:8c4a9f644407ee6fccf3720fd3b727085a2ff109
