2cb0e96cb0Brian Foster <bfoster@redhat.com> says: Here's a bit more fallout and prep. work associated with the folio batch prototype posted a while back [1]. Work on that is still pending so it isn't included here, but based on the iter advance cleanups most of these seemed worthwhile as standalone cleanups. Mainly this just cleans up some of the helpers and pushes some pos/len trimming further down in the write begin path. The fbatch thing is still in prototype stage, but for context the intent here is that it can mostly now just bolt onto the folio lookup path because we can advance the range that is skipped and return the next folio along with the folio subrange for the caller to process.

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.
