Subject: Re: [PATCH] cgroup/cpuset: skip hardwall ancestor scan in v2 mode in cpuset_current_node_allowed()
Date: Fri, 08 May 2026 05:51:29 -1000	[thread overview]
Message-ID: <202d0aa0f8da75986a895ffbd564b78d@kernel.org> (raw)

Hello,

is_in_v2_mode() is also true for v1 mounted with cpuset_v2_mode, where
cpuset.mem_exclusive / cpuset.mem_hardwall are still settable. Would
that be a problem here? cpuset_v2() looks like a tighter fit.

Thanks.
