Instead of a single if statement with multiple conditions, split it into
several if statements testing only one condition at a time and return true
or false immediately after. This makes it more immediate to reason.
The module's text size also slightly decreases, at least with gcc 14.2.0
on x86_64.
Before:
$ size fs/btrfs/btrfs.ko

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.
