Jakub Kicinski says: ==================== netlink: add variable-length / auto integers Add netlink support for "common" / variable-length / auto integers which are carried at the message level as either 4B or 8B depending on the exact value. This saves space and will hopefully decrease the number of instances where we realize that we needed more bits after uAPI is set is stone. It also loosens the alignment requirements, avoiding the need for padding. This mini-series is a fuller version of the previous RFC: https://lore.kernel.org/netdev/20121204.130914.1457976839967676240.davem@davemloft.net/ No user included here. I have tested (and will use) it in the upcoming page pool API but the assumption is that it will be widely applicable. So sending without a user. ==================== Signed-off-by: David S.

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.
