The warning is invalid because the parameter chunksize passed from
ocfs2_info_freefrag_scan_chain-->ocfs2_info_update_ffg is guaranteed to
be positive. So __ilog2_u32 cannot return -1.
fs/ocfs2/ioctl.c: In function 'ocfs2_info_update_ffg':
fs/ocfs2/ioctl.c:411:17: warning: array subscript is below array bounds [-Warray-bounds]

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
