  "details": "In the Linux kernel, the following vulnerability has been resolved:  srcu: Use irq_work to start GP in tiny SRCU  Tiny SRCU's srcu_gp_start_if_needed() directly calls schedule_work(), which acquires the workqueue pool-\u003elock.  This causes a lockdep splat when call_srcu() is called with a scheduler lock held, due to:    call_srcu() [holding pi_lock]     srcu_gp_start_if_needed()       schedule_work() -\u003e pool-\u003elock    workqueue_init() / create_worker() [holding pool-\u003elock]     wake_up_process() -\u003e try_to_wake_up() -\u003e pi_lock  Also add irq_work_sync() to cleanup_srcu_struct() to prevent a use-after-free if a queued irq_work fires after cleanup begins.  Tested with rcutorture SRCU-T and no lockdep warnings.  [ Thanks to Boqun for similar fix in patch \"rcu: Use an intermediate irq_work to start process_srcu()\" ]",
