All operations with stack traces are based on struct stack_trace. That's a horrible construct as the struct is a kitchen sink for input and output. Quite some usage sites embed it into their own data structures which creates weird indirections. There is absolutely no point in doing so. For all use cases a storage array and the number of valid stack trace entries in the array is sufficient. Provide helper functions which avoid the struct stack_trace indirection so the usage sites can be cleaned up.

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.
