Brian Foster 509308b413 xfs: reset dfops to initial state after finish
xfs_defer_init() is currently used in two particular situations. The
first and most obvious case is raw initialization of an
xfs_defer_ops struct. The other case is partial reinit of
xfs_defer_ops on reuse due to iteration.

Most instances of the first case will be replaced by a single init
of a dfops embedded in the transaction. Init calls are still
technically required for the second case because the dfops may have
low space mode enabled or have joined items that need to be reset
before the dfops should be reused.

Since the current dfops usage expects either a final transaction
commit after xfs_defer_finish() or xfs_defer_init() if dfops is to
be reused, we can shift some of the init logic into
xfs_defer_finish() such that the latter returns with a reinitialized
dfops. This eliminates the second dependency noted above such that a
dfops is immediately ready for reuse after an xfs_defer_finish()
without the need to change any calling code.

README

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
