mainlining shenanigans

avoids outputting a series of value: No space left on device The value itself is not wrong but bpf_fd_reuseport_array_lookup_elem() can only return it if the map was created with value_size = 8. There's nothing bpftool can do about it. Instead of repeating this error for every key in the map, print an explanatory warning and a specialized error. example before: key: 00 00 00 00 value: No space left on device key: 01 00 00 00 value: No space left on device key: 02 00 00 00 value: No space left on device Found 0 elements example after: Warning: cannot read values from reuseport_sockarray map with value_size != 8 key: 00 00 00 00 value: <cannot read> key: 01 00 00 00 value: <cannot read> key: 02 00 00 00 value: <cannot read> Found 0 elements Signed-off-by: Benjamin Poirier <bpoirier@suse.com> Reviewed-by: Quentin Monnet <quentin.monnet@netronome.com> Reviewed-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> |

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.
