It's possible for pagecache writeback to split up a large amount of work into smaller pieces for throttling purposes or to reduce the amount of time a writeback operation is pending. Whatever the reason, XFS can end up with a bunch of IO completions that call for the same operation to be performed on a contiguous extent mapping. Since mappings are extent based in XFS, we'd prefer to run fewer transactions when we can. When we're processing an ioend on the list of io completions, check to see if the next items on the list are both adjacent and of the same type. If so, we can merge the completions to reduce transaction overhead. On fast storage this doesn't seem to make much of a difference in performance, though the number of transactions for an overnight xfstests run seems to drop by ~5%. Signed-off-by: Darrick J.

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.
