  "message": "cgroup: remove cgroup_lock_is_held()\n\nWe don\u0027t want controllers to assume that the information is officially\navailable and do funky things with it.\n\nThe only user is task_subsys_state_check() which uses it to verify RCU\naccess context.  We can move cgroup_lock_is_held() inside\nCONFIG_PROVE_RCU but that doesn\u0027t add meaningful protection compared\nto conditionally exposing cgroup_mutex.\n\nRemove cgroup_lock_is_held(), export cgroup_mutex iff CONFIG_PROVE_RCU\nand use lockdep_is_held() directly on the mutex in\ntask_subsys_state_check().\n\nWhile at it, add parentheses around macro arguments in\ntask_subsys_state_check().\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\n",
