The changes to skip discards of speculative preallocation and unwritten extents introduced several new wrapper functions through the bunmapi -> extent free codepath to reduce churn in all of the associated callers. In several cases, these wrappers simply toggle a single flag to skip or not skip discards for the resulting blocks. The explicit _nodiscard() wrappers for such an isolated set of callers is a bit overkill. Kill off these wrappers and replace with the calls to the underlying functions in the contexts that need to control discard behavior. Retain the wrappers that preserve the original calling conventions to serve the original purpose of reducing code churn. This is a refactoring patch and does not change behavior.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
