Josef Bacik 0b08851fda Btrfs: optimize reada_for_balance ... This patch does two things. First we no longer explicitly read in the blocks we're trying to readahead. For things like balance_level we may never actually use the blocks so this just adds uneeded latency, and balance_level and split_node will both read in the blocks they care about explicitly so if the blocks need to be waited on it will be done there. Secondly we no longer drop the path if we do readahead, we just set the path blocking before we call reada_for_balance() and then we're good to go. Hopefully this will cut down on the number of re-searches. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com>		2013-07-01 08:52:32 -04:00
