commit b611fddc0435738e64453bbf1dadd4b12a801858 upstream. Exact minlen allocations only exist as an error injection tool for debug builds. Currently this is implemented using ifdefs, which means the code isn't even compiled for non-XFS_DEBUG builds. Enhance the compile test coverage by always building the code and use the compilers' dead code elimination to remove it from the generated binary instead. The only downside is that the alloc_minlen_only field is unconditionally added to struct xfs_alloc_args now, but by moving it around and packing it tightly this doesn't actually increase the size of the structure.

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.
