It won't apply to pre-4.14 kernels because of the fine-grained locking changes, but the same issue exists there and I suspect it would cause the same crash. Do you want me to send a separate patch for pre-4.14? Also, I'm going to send a v2 for this because it can be a bit cleaner (avoiding a deref).

I have a script that picks up everything the syzbot finds and tries to backport them, after they are applied in Linus's tree. Might as well catch things before we have to rely on my script :) thanks, greg k-h ___ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
