allocate_resource() accepts ->alignf() callback to perform custom alignment beyond constraint->align. If alignf is NULL, simple_align_resource() is used which only returns avail->start (no change). Using avail->start directly is natural and can be done with a conditional in __find_resource_space() instead which avoids unnecessarily using callback. It makes the code inside __find_resource_space() more obvious and removes the need for the caller to provide constraint->alignf unnecessarily. This is preparation for exporting find_resource_space().

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.
