I will send it out later on today.
Since I haven't received it, here comes an update. Changes since v1: Tetsuo Handa found that the PTR_ERR() access in usbip_prepare_threads() in v1 was wrong, and fixed it in v2. Changes since v2: The kernel test robot [off-list ref] found the same error using scripts/coccinelle/tests/odd_ptr_err.cocci and Julia Lawall [off-list ref] sent us a patch, but nothing changed because that error was already fixed in v2. Changes since v3: Reduce lines changed in drivers/usb/usbip/stub_dev.c . Split into 12 patches.
