If anyone has any objections, please let me know. ------------------ From: Dave Kleikamp [ Upstream commit 463d439becb81383f3a5a5d840800131f265a09c ] atomic_pool_expand iteratively tries the allocation while decrementing the page order. There is no need to issue a warning if an attempted allocation fails.
