Btrfs: optimize read_block_for_search This patch does two things, first it only does one call to btrfs_buffer_uptodate() with the gen specified instead of once with 0 and then again with gen specified. The other thing is to call btrfs_read_buffer() on the buffer we've found instead of dropping it and then calling read_tree_block(). This will keep us from doing yet another radix tree lookup for a buffer we've already found. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com>
