They are all triggered by admin action, or unconditionally upon boot. OTOH I think that an useful message that's currently missing would be when the static_key_enable() is triggered in auto mode. Bonus points for including the name of the process and the stat file that was read. However static_key_enable() returns void and not whether it actually flipped the switch, so it's not trivial. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
