That's here:
1572 ret = __btrfs_add_delayed_deletion_item(node, item);
1573 if (unlikely(ret)) {
1574 btrfs_err(root->fs_info, "err add delayed dir index
item(index: %llu) "
1575 "into the deletion tree of the delayed
node"
1576 "(root id: %llu, inode id: %llu, errno:
%d)",
1577 index, node->root->objectid,
node->inode_id,
1578 ret);
1579 BUG();
1580 }
As far as I can tell, the only way that __btrfs_add_delayed_deletion_item()
will fail is with -EEXIST, which would be a bug, but your trace doesn't include
the btrfs_err message right before the BUG(). Do you still have that dmesg
lying around just to be sure?
