The compilation with W=1 generates the following warnings:
fs/btrfs/sysfs.c:1630:6: warning: variable 'ret' set but not used [-Wunused-but-set-variable]
1630 | int ret;
| ^~~
fs/btrfs/sysfs.c:1629:6: warning: variable 'features' set but not used [-Wunused-but-set-variable]
1629 | u64 features;
| ^~~~~~~~
[ The unused variables are leftover from e410e34fad91 ("Revert "btrfs:
synchronize incompat feature bits with sysfs files""), which needs
to be properly fixed by moving feature bit manipulation from the sysfs
context. Silence the warning to save pepople time, we got several
reports. ]

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.
