UBSAN found the following issue:
================================================================================
UBSAN: array-index-out-of-bounds in fs/reiserfs/journal.c:4166:22
index 1 is out of range for type '__le32 [1]'
This is because struct reiserfs_journal_desc uses 1-element array for
dynamically sized array member, j_realblock.
This patch fixes this issue by replacing the 1-element array member with C99
style flex-array. This patch also fixes the same issue in struct
reiserfs_journal_commit as the same manner.
Fixes: f466c6fdb3 ("move private bits of reiserfs_fs.h to fs/reiserfs/reiserfs.h")

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.
