So you want to set/clear this no_warn attr through the procfs or sysfs interface, so that you can easily disable/enable the slab/page fault warning message from the user mode. Right?

Yes, just like:

echo 1 > /sys/kernel/debug/failslab/no_warn #disable message echo 0 > /sys/kernel/debug/failslab/no_warn #enable message

You can already do that:

echo 0 > /sys/kernel/debug/failslab/verbose #disable message
