Avoid this potential UaF situation by adding a new cpuset_v2_modeflag which is set when the cpuset_v2_mode mount option is used. Thisflag is written into only when cpuset_bind() is being called with astable cpuset_cgrp_subsys.root value. The is_in_v2_mode() helper ismodified to read the new cpuset_v2_mode flag instead of accessingcpuset_cgrp_subsys.root directly.\n[1]
