Hi, >> And the return value(-ENODEV) will be returned to error handler. >> uas_eh_device_reset_handler->usb_reset_device -> usb_reset_and_verify_device (return -ENODEV) Then I wrote that commit message that we think even if we ignore "ENODEV" in post reset to avoid hang issue but the error will also be reported to error handler. >> #If ignore an error and the error will not be reported then it is not good. > >Well, what do we do now? Are you saying that the state model SCSI is using is wrong? No, it is not wrong. But I think we may want to prevend hang by sleep peocess with continuing to take a lock at blk_execute_rq() from usb_unbind_and_rebind_marded_interfaces(). Regards, Kento Kobayashi
