[Devel] [PATCH hci-8.1 1/2] mempolicy: prohibit mbind and set_mempolicy_home_node in VE

[no-reply at sashiko.virtuozzo.com]

> A CT is meant to see a kernel without NUMA support: in a non-super VE
> the NUMA API syscalls return -ENOSYS, as they do in a kernel built
> without CONFIG_NUMA.
> 
> Return -ENOSYS from mbind(2) and set_mempolicy_home_node(2) at the
> start of the handler, before any argument check, as the other NUMA API
> syscalls do.
> 
> Fixes: a803a5b2ea97 ("mempolicy: prohibit all NUMA API syscalls in VE")
> https://virtuozzo.atlassian.net/browse/VSTOR-153679
> 
> Feature: mm: prohibit NUMA API inside CT
