And, does this one show up as /sys/module/kfence/parameters/fault? Having the ability to tweak this behavior at run time, without requiring a system reboot, could be really useful for people unexpectedly triggering kernel panics across a fleet of servers, and deciding they would rather not. --=20 All Rights Reversed.
