kdb_read_get_key() has extremely complex break/continue control flow managed by state variables and is very hard to review or modify. In particular the way the escape sequence handling interacts with the general control flow is hard to follow. Separate out the escape key handling, without changing the control flow. This makes the main body of the code easier to review.

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.
