====================
bpf: permit multiple bpf attachments for a single perf tracepoint event
This patch set adds support to permit multiple bpf prog attachments
for a single perf tracepoint event. Patch 1 does some cleanup such
that perf_event_{set|free}_bpf_handler is called under the
same condition. Patch 2 has the core implementation, and
Patch 3 adds a test case.
Changelogs:
v2 -> v3:
. fix compilation error.
v1 -> v2:
. fix a potential deadlock issue discovered by Daniel.
. fix some coding style issues.

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.
