We still keep a limit because anything above 2048 sectors really rendered negligible speed improvements, so we will simply ignore that.

Overview In current USB/IP implementation, event kernel threads are created for each port. The functions of the threads are closing connection and error handling so they don't have not so many events to handle. There's no need to have thread for each port. BEFORE) vhci side - VHCI_NPORTS(8) threads are created. $ ps aux | grep usbip root 10059 0.0 0.0 0 0 ? S 17:06 0:00 [usbip_eh] root 10060 0.0 0.0 0 0 ?

S 17:06 0:00 [usbip_eh] BEFORE) stub side - threads will be created every bind operation. $ ps aux | grep usbip root 8368 0.0 0.0 0 0 ? S 17:56 0:00 [usbip_eh] root 8399 0.0 0.0 0 0 ? S 17:56 0:00 [usbip_eh] This patch put event threads of stub and vhci driver as one workqueue. AFTER) only one event threads in each vhci and stub side. $ ps aux | grep usbip root 10457 0.0 0.0 0 0 ? S< 17:47 0:00 [usbip_event] 2. Modification to usbip_event.c BEFORE) kernel threads are created in usbip_start_eh(). AFTER) one workqueue is created in new usbip_init_eh(). Event handler which was main loop of kernel thread is modified to workqueue handler. Events themselves are stored in struct usbip_device - same as before. usbip_devices which have event are listed in event_list. The handler picks an element from the list and wakeup usbip_device. The wakeup method is same as before. usbip_in_eh() substitutes statement which checks whether functions are called from eh_ops or not. In this function, the worker context is used for the checking. The context will be set in a variable in the beginning of first event handling. usbip_in_eh() is used in event handler so it works well. 3. Modifications to programs using usbip_event.c Initialization and termination of workqueue are added to init and exit routine of usbip_core respectively. A. version info v2) # Merged 1/2 event handler itself and 2/2 user programs because of auto build fail at 1/2 casued unmodified user programs in 1/2.

Devices that after having been reset during resume need to be rebound due to a missing reset_resume callback, are now left in a suspended state. This specifically broke resume of common USB-serial devices, which are now unusable after system suspend (until disconnected and reconnected) when USB persist is enabled. During resume, usb_resume_interface will set the needs_binding flag for such interfaces, but unlike system resume, run-time resume does not honour it.
