commit1b83ec057dupstream. Make 'ui->data_len' aligned with 8 bytes before it is assigned to dirtied_ino_d. Since 8871d84c8f8b0c6b("ubifs: convert to fileattr") applied, 'setflags()' only affects regular files and directories, only xattr inode, symlink inode and special inode(pipe/char_dev/block_dev) have none- zero 'ui->data_len' field, so assertion '!(req->dirtied_ino_d & 7)' cannot fail in ubifs_budget_space(). To avoid assertion fails in future evolution(eg. setflags can operate special inodes), it's better to make dirtied_ino_d 8 bytes aligned, after all aligned size is still zero for regular files.

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.
