If firewire-sbp2 starts a login to a target that doesn't complete ORBs in a timely manner (and has to retry the login), and the module is removed before the operation times out, you end up with a null-pointer dereference and a kernel panic. [SR: This happens because sbp2_target_get/put() do not maintain module references. scsi_device_get/put() do, but at occasions like Chris describes one, nobody holds a reference to an SBP-2 sdev.] This patch cancels pending work for each unit in sbp2_remove(), which hopefully means there are no extra references around that prevent us from unloading. This fixes my crash. Signed-off-by: Chris Boot <bootc@bootc.net> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> |
