Roman Gushchin fe4d44b23f libbpf: prefer global symbols as bpf program name source
Libbpf picks the name of the first symbol in the corresponding
elf section to use as a program name. But without taking symbol's
scope into account it may end's up with some local label
as a program name. E.g.:

$ bpftool prog
1: type 15  name LBB0_10    tag 0390a5136ba23f5c
	loaded_at Dec 07/17:22  uid 0
	xlated 456B  not jited  memlock 4096B

Fix this by preferring global symbols as program name.

For instance:
$ bpftool prog
1: type 15  name bpf_prog1  tag 0390a5136ba23f5c
	loaded_at Dec 07/17:26  uid 0
	xlated 456B  not jited  memlock 4096B

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
