Its next request is then\nsilently dropped: rtsx_usb_ms_request() skips schedule_work() once eject\nis set, and drv_remove's cancel_work_sync() can also cancel a queued\nhandle_req before it picks the request up. Nobody completes\ncard->mrq_complete.\n\nOnce memstick core waits for requests without a timeout (\"memstick: core:\nwait for request completion before freeing card\"), this hangs removal:\nmemstick_check() never returns and memstick_remove_host() blocks in\nflush_workqueue():\n\n  INFO: task kworker/u10:3:65 blocked for more than 20 seconds.\n  Workqueue: kmemstick memstick_check\n   __wait_for_common\n   memstick_check\n\n  INFO: task kworker/1:1:33 blocked for more than 20 seconds.\n  Workqueue: usb_hub_wq hub_event\n   __flush_workqueue\n   memstick_remove_host\n   rtsx_usb_ms_drv_remove\n\nNever drop a request. rtsx_usb_ms_request() always schedules handle_req,\nand handle_req fails requests with -ENOMEDIUM once eject is set, without\ntouching the device. drv_remove flushes handle_req instead of cancelling\nit, and cancels it only after memstick_remove_host(), when no new\nrequest can arrive, so it cannot run on a freed host.\n\nThe host_mutex drain in drv_remove is removed: handle_req always leaves\nhost->req NULL when it finishes, so the drain never had anything to do,\nand it would now race with handle_req."
