Hi. The scenario is a PCI driver on a kernel 3.19.2: is it possible, in case pending_signal(current) is true, to return -ERESTARTSYS to insmod process, in order to get it restart (as expectable)? After some attempts (with pending_signal(current) being true), it seems that -ERESTARTSYS is caught by the "pci layer" that complains saying something like "probing failed .. unexpectedly returns -512" and nothing is restarted as expected. Does insmod disables it explicitly? If so, how to get a similar "restart-behaviour"? Thanks
