Callers currently have to round out the size of buffers to match the aligment constraints of log iovecs and xlog_write(). They should not need to know this detail, so introduce a new function to calculate the iovec length (for use in ->iop_size implementations). Also modify xlog_finish_iovec() to round up the length to the correct alignment so the callers don't need to do this, either. Convert the only user - inode forks - of this alignment rounding to use the new interface.

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.
