With both CONFIG_XFS_DEBUG and CONFIG_XFS_WARN disabled, the only reference to local variable "error" in xfs_bmap_compute_alignments() gets eliminated during pre-processing stage of the compilation process. This causes the compiler to generate a "set but not used" warning. Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Chandan Babu R <chandanrlinux@gmail.com> Reviewed-by: Darrick J.

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.
