For a list of files, their metadata is stored in fragmented disk space and metadata read is a sync operation, which impacts the efficiency of readahead much. The patches try to add meatadata readahead for btrfs. In btrfs, metadata is stored in btree_inode. Ideally, if we could hook the inode to a fd so we could use
