Zygo Blaxell	72cc9c2b60	ExtentWalker: increase efficiency for typical btrfs extent sizes ... Perf was blaming more than 50% of cycles on TREE_SEARCH_V2. strace showed 4 TREE_SEARCH_V2 calls for every pread in grow_backward(). Fix by increasing the extent fetch batch size so it is more likely to include the desired items in the first fetch attempt. This removes TREE_SEARCH_V2 from the top 10 list of cycle consumers.
