====================
hi,
sending change we discussed some time ago [1] to get rid of
some deprecated functions we use in perf prologue code.
Despite the gloomy discussion I think the final code does
not look that bad ;-)
This patchset removes following libbpf functions from perf:
bpf_program__set_prep
bpf_program__nth_fd
struct bpf_prog_prep_result
v5 changes:
- squashed patches together so we don't break bisection [Arnaldo]
v4 changes:
- fix typo [Andrii]
v3 changes:
- removed R0/R1 zero init in libbpf_prog_prepare_load_fn,
because it's not needed [Andrii]
- rebased/post on top of bpf-next/master which now has
all the needed perf/core changes
v2 changes:
- use fallback section prog handler, so we don't need to
use section prefix [Andrii]
- realloc prog->insns array in bpf_program__set_insns [Andrii]
- squash patch 1 from previous version with
bpf_program__set_insns change [Daniel]
- patch 3 already merged [Arnaldo]
- added more comments
thanks,
jirka

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.
