Name:Post an RCU callback to be invoked after the end of an RCU grace* period. But since we have but one CPU, that would be after any* quiescent state.

Proto:void call_rcu(struct callback_head *head, rcu_callback_t func)

Type:void

Parameter:

TypeParameterName
struct callback_head *head
rcu_callback_tfunc
137  debug_rcu_head_queue()/debug_rcu_head_unqueue() are used internally* by call_rcu() and rcu callback execution, and are therefore not part* of the RCU API. These are in rcupdate.h because they are used by all* RCU implementations.
138  func = func
139  next = NULL
141  local_irq_save(flags)
142  ->next pointer of last CB. = head
143  ->next pointer of last CB. = next
144  local_irq_restore(flags)
146  If Value for the false possibility is greater at compile time(s_idle_task - is the specified task an idle task?*@p: the task in question.* Return: 1 if @p is an idle task. 0 otherwise.) Then

audit_mark_put_chunkDrop reference to the chunk that was held by the mark. This is the reference* that gets dropped after we've removed the chunk from the hash table and we* use it to make sure chunk cannot be freed before RCU grace period expires.

put_objectDecrement the object use_count. Once the count is 0, free the object using* an RCU callback. Since put_object() may be called via the kmemleak_free() ->* delete_object() path, the delayed RCU freeing ensures that there is no
