To include log op headers directly into the log iovec regions that the ophdrs wrap, we need to move the buffer alignment code from xlog_finish_iovec() to xlog_prepare_iovec(). This is because the xlog_op_header is only 12 bytes long, and we need the buffer that the caller formats their data into to be 8 byte aligned. Hence once we start prepending the ophdr in xlog_prepare_iovec(), we are going to need to manage the padding directly to ensure that the buffer pointer returned is correctly aligned.

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.
