From: Johannes Thumshirn <johannes.thumshirn@xxxxxxx> Since we have no write pointer in conventional zones, we cannot determine allocation offset from it. Instead, we set the allocation offset after the highest addressed extent. This is done by reading the extent tree in btrfs_load_block_group_zone_info(). However, this function is called from btrfs_read_block_groups(), so the read lock for the tree node can recursively taken.
