> The age action with flows creation could be supported on the multiple
> threads. The age pools were created to manage the age resources, if
> there is no room in the current pool then resize the age pool to the new
> pool size and free the old one.
> 
> There's a race condition while one thread resizes the age pool and the
> old pool resource be freed, and another thread query the age action
> value of the old pool so the queried value is invalid.
> 
> This patch uses the read-write lock to protect the pool resource while
> resizing and query.
