For prog array maps, the type of the owner program, and the JIT-ed state
of that program, are available from the file descriptor information
under /proc. Add them to "bpftool map show" output. Example output:
# bpftool map show
158225: prog_array name jmp_table flags 0x0
key 4B value 4B max_entries 8 memlock 4096B
owner_prog_type flow_dissector owner jited
# bpftool --json --pretty map show
[{
"id": 1337,
"type": "prog_array",
"name": "jmp_table",
"flags": 0,
"bytes_key": 4,
"bytes_value": 4,
"max_entries": 8,
"bytes_memlock": 4096,
"owner_prog_type": "flow_dissector",
"owner_jited": true
}
]
As we move the table used for associating names to program types,
complete it with the missing types (lwt_seg6local and sk_reuseport).
Also add missing types to the help message for "bpftool prog"
(sk_reuseport and flow_dissector).

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.
