  "message": "usb/isp1760: Improve urb queueing, get rid of BUG():s in normal code paths\n\nThis patch replaces the code that handles qtds. Intead of directly allocating\nchip mem and chip slot, enqueue the transfer in a list of queue heads. Use\na centralized function enqueue_qtds() to prioritize and enqueue transfers.\n\nThis removes all of the interrupt context BUG() calls when out of chip\nmem or transfer slots. It also makes it possible to efficiently use the\ndual-port mem on the chip for double-buffered transfers, which improve\ntransfer times to/from/between usb sticks by about 40 % on my HW.\n\nWith this patch it should also be possible to handle qtd scheduling outside\nof the interrupt handler, for significantly improved kernel latency. I have\nnot implemented this since there are some locking issues which I haven\u0027t\nhad time to look at.\n\nSigned-off-by: Arvid Brodin \u003carvid.brodin@enea.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n",
