At insert_new_root(), instead of doing a BUG_ON() in case we fail to record the tree mod log operation, just return the error to the callers after releasing the allocated tree block. At this point we haven't made any changes to the b+tree, so we haven't left it in an inconsistent state and therefore have no need to abort the transaction. All we need to do is to unlock and free the extent buffer we just allocated with the purpose of making it the new root.

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.
