The online repair block reaping code employs static limits to decide if it's time to roll the transaction or finish the deferred item chains to avoid overflowing the scrub transaction's reservation. However, the use of static limits aren't great -- btree blocks are assumed to be scattered around the AG and the buffers need to be invalidated, whereas COW staging extents are usually contiguous and do not have buffers. We would like to configure the limits dynamically. To get ready for this, reorganize struct xreap_state to store dynamic limits, and add helpers to hide some of the details of how the limits are enforced. Also rename the "xreap roll" functions to include the word "binval" because they only exist to decide when we should roll the transaction to deal with buffer invalidations. No functional changes intended here. Signed-off-by: "Darrick J. Wong" <djwong@kernel.org> Reviewed-by: Christoph Hellwig <hch@lst.de>
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 reStructuredText 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.
