Jens Axboe cf9536e550 io_uring/kbuf: enable bundles for incrementally consumed buffers
The original support for incrementally consumed buffers didn't allow it
to be used with bundles, with the assumption being that incremental
buffers are generally larger, and hence there's less of a nedd to
support it.

But that assumption may not be correct - it's perfectly viable to use
smaller buffers with incremental consumption, and there may be valid
reasons for an application or framework to do so.

As there's really no need to explicitly disable bundles with
incrementally consumed buffers, allow it. This actually makes the peek
side cheaper and simpler, with the completion side basically the same,
just needing to iterate for the consumed length.

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.
