Allow nbcon consoles to print messages in the legacy printk() caller context (printing via unlock) by integrating them into console_flush_all(). The write_atomic() callback is used for printing. Provide nbcon_legacy_emit_next_record(), which acts as the nbcon variant of console_emit_next_record(). Call this variant within console_flush_all() for nbcon consoles. Since nbcon consoles use their own @nbcon_seq variable to track the next record to print, this also must be appropriately handled in console_flush_all(). Note that the legacy printing logic uses @handover to detect handovers for printing all consoles. For nbcon consoles, handovers/takeovers occur on a per-console basis and thus do not cause the console_flush_all() loop to abort.

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 reStructuredText 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.
