From: Chen Ridong Date: Wed, 14 Jan 2026 01:51:29 +0000 (+0000) Subject: cpuset: Fix missing adaptation for cpuset_is_populated X-Git-Tag: v6.18.13~16 X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=98d91080517d4c642820b5d8219cb759ddaf79b7;p=thirdparty%2Fkernel%2Fstable.git cpuset: Fix missing adaptation for cpuset_is_populated Commit b1bcaed1e39a ("cpuset: Treat cpusets in attaching as populated") was backported to the long‑term support (LTS) branches. However, because commit d5cf4d34a333 ("cgroup/cpuset: Don't track # of local child partitions") was not backported, a corresponding adaptation to the backported code is still required. To ensure correct behavior, replace cgroup_is_populated with cpuset_is_populated in the partition_is_populated function.
