The nbcon consoles will have two callbacks to be used for different contexts. In order to determine if an nbcon console is usable, console_is_usable() must know if it is a context that will need to use the optional write_atomic() callback. Also, nbcon_emit_next_record() must know which callback it needs to call. Add an extra parameter @use_atomic to console_is_usable() and nbcon_emit_next_record() to specify this. Since so far only the write_atomic() callback exists, @use_atomic is set to true for all call sites. For legacy consoles, @use_atomic is not used.

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.
