Btrfs has the following different extent_io_trees used: - fs_info::free_extents[2] - btrfs_inode::io_tree - for both normal inodes and the btree inode - btrfs_inode::io_failure_tree - btrfs_transaction::dirty_pages - btrfs_root::dirty_log_pages If we want to trace changes in those trees, it will be pretty hard to distinguish them. Instead of using hard-to-read pointer address, this patch will introduce a new member extent_io_tree::owner to track the owner. This modification needs all the callers of extent_io_tree_init() to accept a new parameter @owner. This patch provides the basis for later trace events.
