Inode buffers always have write IO callbacks, so by marking them directly we can avoid needing to attach ->b_iodone functions to them. This avoids an indirect call, and makes future modifications much simpler. While this is largely a refactor of existing functionality, we broaden the scope of the flag to beyond where inodes are explicitly attached because future changes need to know what type of log items are attached to the buffer. Adding this buffer flag may invoke the inode iodone callback in cases where it wouldn't have been previously, but this is not a functional change because the callback is identical to the normal buffer write iodone callback when inodes are not attached.

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.
