Alexei Starovoitov a3d697ff8d Merge branch 'libbpf: add legacy uprobe support'
Andrii Nakryiko says:

====================

Implement libbpf support for attaching uprobes/uretprobes using legacy
tracefs interfaces. This is a logical complement to recently landed legacy
kprobe support ([0]). This patch refactors existing legacy kprobe code to be more
uniform with uprobe code as well, making the logic easier to compare and
follow.

This patch set also fixes two bugs recently found by Coverity in legacy kprobe
handling code, and thus subsumes previously submitted two patches ([1]):
original patch #1 is kept as is, while original patch #2 was dropped because
patch #3 of the current series refactors and fixes affected code.

  [1] https://patchwork.kernel.org/project/netdevbpf/list/?series=549977&state=*

v1->v2:
  - drop 'legacy = true' debug left-over and explain legacy check (Alexei).

README

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.
