"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmm/vmscan: report RCU-tasks quiescent states in shrink_lruvec()\n\nI am seeing some rcu_tasks stalls in the Meta fleet during reclaim.\n\n INFO: rcu_tasks detected stalls on tasks:\n\t0000000088620d09: .. nvcsw: 6735/6735 holdout: 1 idle_cpu: -1/8\n\ttask:GlobalCPUThread state:R running task pid:2552016 tgid:2524552\n Call Trace:\n shrink_lruvec\n mem_cgroup_iter\n shrink_node\n do_try_to_free_pages\n try_to_free_pages\n __alloc_frozen_pages_noprof\n alloc_pages_noprof\n pte_alloc_one\n __pte_alloc\n handle_mm_fault\n\nNothing promises direct reclaim returns in bounded time, and the scan loop\nin shrink_lruvec() only calls cond_resched(), which is a no-op on\nPREEMPTION kernels. Involuntary preemption is not a Tasks-RCU quiescent\nstate, so the reclaiming task never reports one and becomes a holdout.\n\nUpgrade it to cond_resched_tasks_rcu_qs(), which reports a quiescent state\neven when cond_resched() does nothing.\n\nPS: This has been discussed in [1]"
