There is one report of fuzzed image which leads to BUG_ON() in btrfs_delete_delayed_dir_index(). Although that fuzzed image can already be addressed by enhanced extent-tree error handler, it's still better to hunt down more BUG_ON(). This patch will hunt down two BUG_ON()s in btrfs_delete_delayed_dir_index(): - One for error from btrfs_delayed_item_reserve_metadata() Instead of BUG_ON(), we output an error message and free the item. And return the error. All callers of this function handles the error by aborting current trasaction. - One for possible EEXIST from __btrfs_add_delayed_deletion_item() That function can return -EEXIST. We already have a good enough error message for that, only need to clean up the reserved metadata space and allocated item. To help above cleanup, also modifiy __btrfs_remove_delayed_item() called in btrfs_release_delayed_item(), to skip unassociated item.

README
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.
