There is a BUG_ON() in btrfs_csum_one_bio() to catch code logic error. It has indeed caught several bugs during subpage development. But the BUG_ON() itself will bring down the whole system which is an overkill. Replace it with a WARN() and exit gracefully, so that it won't crash the whole system while we can still catch the code logic error.

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.
