[Devel] [PATCH hci-8.1 v2 3/4] shmem: reject the mpol= mount option in VE

[no-reply at sashiko.virtuozzo.com]

> A CT is meant to see a kernel without NUMA support, so the NUMA API
> syscalls return -ENOSYS in a non-super VE. The tmpfs mpol= mount option
> still lets a CT set a NUMA memory policy for all files of a tmpfs
> mount.
> 
> Reject mpol= in a non-super VE the way a kernel built without
> CONFIG_NUMA does: the mount fails with -EINVAL and "Unsupported
> parameter 'mpol'".

> 
> Feature: mm: prohibit NUMA API inside CT
