Right now buffer cloning is an all-or-nothing kind of thing - either the whole table is cloned from a source to a destination ring, or nothing at all. However, it's not always desired to clone the whole thing. Allow for the application to specify a source and destination offset, and a number of buffers to clone. If the destination offset is non-zero, then allocate sparse nodes upfront. Signed-off-by: Jens Axboe <axboe@kernel.dk>
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.
