Date: Tue, 18 Sep 2012 10:16:56 +0530 From: navin patidar <navinp@...c.in> To: gregkh@...uxfoundation.org, mfm@...eddisk.com Cc: linux-usb@...r.kernel.org, devel@...verdev.osuosl.org, linux-kernel@...r.kernel.org, navin patidar <navinp@...c.in> Subject: [PATCH] staging: usbip: vhci_hcd: Fixed oops during removal of vhci_hcd In response to "usbip detach -p [port_number]" user command,vhci_shoutdown_connection gets executed which kills tcp_tx,tcp_rx kernel threads and then vhci_device_reset resets all usb_device struct variables except kernel thread pointers. so, at the time of vhci_hcd removal vhci_shoutdown_connection tries to kill kernel threads which are already killed.
