Subject: mm/mempolicy: failed to disable numa balancing
Date: Fri, 2 Dec 2022 22:16:30 +0800
The kernel fails to disable numa balancing policy permanently when the
user passes <numa_balancing=disable> to the boot cmdline parameters. The
numabalancing_override variable is 1 for enable -1 for disable. So,
!numabalancing_override will always be true, which causes this bug.
