struct work_struct *work
557  mutex_lock( & This protects kprobe_table and optimizing_list )
558  cpus_read_lock()
559  mutex_lock( & mutex protecting text section modification (dynamic code patching).* some users need to sleep (allocating memory...) while they hold this lock.* Note: Also protects SMP-alternatives modification on x86.)
561  mutex_lock( & Mutex protects:* 1) List of modules (also safely readable with preempt_disable),* 2) module_use links,* 3) module_addr_min/module_addr_max.* (delete and add uses RCU list operations). )
567  Unoptimize (replace a jump with a breakpoint and remove the breakpoint* if need) kprobes listed on unoptimizing_list.
578  synchronize_rcu_tasks()
581  Optimize (replace a breakpoint with a jump) kprobes listed on* optimizing_list.
584  Reclaim all kprobes on the free_list
