Quentin Monnet says: ==================== For passing device functions for offloaded eBPF programs, there used to be no place where to store the pointer without making the non-offloaded programs pay a memory price. As a consequence, three functions were called with ndo_bpf() through specific commands. Now that we have struct bpf_offload_dev, and since none of those operations rely on RTNL, we can turn these three commands into hooks inside the struct bpf_prog_offload_ops, and pass them as part of bpf_offload_dev_create(). This patch set changes the offload architecture to do so, and brings the relevant changes to the nfp and netdevsim drivers. ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org>
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.
