<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">A couple of general points:
1) I mostly overlooked this in the ao2 container improvements, but you have a real love for the word "prnt" for things. Is there any reason you don't just use the entire word "print"?
2) astobj2.c absolutely needs to be broken up. Its size is nowhere near as bad as certain other source files, but it has reached the point where it is doing too many disparate things all in a single file. I think it should be broken into four files:
a) A file that does basic object allocation, refcount, and locking functions.
b) A file that contains base container operations that are container-type agnostic.
c) A file that contains hash table-specific container functions.
d) A file that contains rbtree-specific container functions.
This will be much easier to do now than later.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">1) My editor thinks print() is a library function and highlights it that way. Also print() would be very close to printf(). All the other uses inside longer identifiers is just consistency.
2) That can be done in another patch. There are going to be some scoping issues breaking this up. ao2_container_clone() looks into the ao2 object to get configuration information. The RTTI code also slightly violates scoping.</pre>

What would probably be even better would be constants called LEFT and RIGHT to be more clear. That way, you wouldn't need all the "Go left" and "Go right" comments in this function.</pre>

N = node
Ch = child
p = parent
Same goes for the picture of the right rotation down below.</pre>

* Add CLI command "astobj2 container dump <name>"
* Added ao2_container_dump() so the container could be dumped by other
modules for debugging purposes.
* Changed ao2_container_stats() so it can be used by other modules like
ao2_container_check() for debugging purposes.
