Checking for availability in bi_size in a function that attempts to merge into an existing segment is a bit odd, as the limit also applies when adding a new segment. This code works fine as we always call __bio_try_merge_page, but contributes to sub-optimal calling conventions and doesn't lead to clear code. Move it to two of the callers instead, the third one already has a more strict check that includes max_hw_segments anyway.

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.
