If we fail to add a delayed dir index item because there's already another item with the same index number, we print an error message (and then BUG). However that message isn't very helpful to debug anything because we don't know what's the index number and what are the values of index counters in the inode and its delayed inode (index_cnt fields of struct btrfs_inode and struct btrfs_delayed_node). So update the error message to include the index number and counters. We actually had a recent case where this issue was hit by a syzbot report (see the link below).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
