Subject: pull-request v2: bpf-next 2021-12-10
Hi David, hi Jakub,
The following pull-request contains BPF updates for your *net-next* tree.
There are three merge conflicts between bpf and bpf-next:
1. Documentation/bpf/index.rst. Please Just drop the libbpf and BTF sections,
so that the resulting content is like this:
[...]
This kernel side documentation is still work in progress.
The Cilium project also maintains a `BPF and XDP Reference Guide`_
that goes into great technical depth about the BPF Architecture.
.. toctree::
:maxdepth: 1
instruction-set
verifier
[...]
2. kernel/bpf/btf.c. There was a big chunk of code added at the end, but git
is confused about #endif. Please keep the original #endif (corresponding to
#ifdef CONFIG_DEBUG_INTO_BTF_MODULES) and all the newly added code goes to
the end of the file:

3. tools/lib/bpf/libbpf.c, attr->log_level should be replaced with
extra_log_level, but otherwise 4-parameter invocation of btf_gen__init()
wins:
