Username: siweixiang
Origin: https://bugs.openwrt.org/index.php?do=details&task_id=2326
use ‘make kernel_menuconfig’ to configure page_owner function and add page_owner=on to kernel boot cmdline
compile, and update the Firefly FireWRT board
login into the system, cat ‘/sys/kernel/debug/page_owner’, no output
