When xfs_defer_capture extracts the deferred ops and transaction state from a transaction, it should record the remaining block reservations so that when we continue the dfops chain, we can reserve the same number of blocks to use. We capture the reservations for both data and realtime volumes. This adds the requirement that every log intent item recovery function must be careful to reserve enough blocks to handle both itself and all defer ops that it can queue. On the other hand, this enables us to do away with the handwaving block estimation nonsense that was going on in xlog_finish_defer_ops. 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.
