So no extent tree problems, all DIR_ITEMS. It's OK for you to use the following branch, and execute "btrfs check --repair" to fix the fs: https://github.com/adam900710/btrfs-progs/tree/check-next Please note that, current upstream btrfs-progs won't fix it, only that branch contains the fixing commits.
