kernel-patches/bpf failed with error:
Running bpftool checks...
Comparing /data/users/ast/net-next/tools/include/uapi/linux/bpf.h (bpf_map_type) and
/data/users/ast/net-next/tools/bpf/bpftool/map.c (do_help() TYPE):
{'cgroup_storage_deprecated', 'cgroup_storage'}
Comparing /data/users/ast/net-next/tools/include/uapi/linux/bpf.h (bpf_map_type) and
/data/users/ast/net-next/tools/bpf/bpftool/Documentation/bpftool-map.rst (TYPE):
{'cgroup_storage_deprecated', 'cgroup_storage'}
The selftests/bpf/test_bpftool_synctypes.py runs checking in the above.
The failure is introduced by Commit c4bcfb38a95e("bpf: Implement cgroup storage available
to non-cgroup-attached bpf progs"). The commit introduced BPF_MAP_TYPE_CGROUP_STORAGE_DEPRECATED
which has the same enum value as BPF_MAP_TYPE_CGROUP_STORAGE.
In test_bpftool_synctypes.py, one test is to compare uapi bpf.h map types and
bpftool supported maps. The tool picks 'cgroup_storage_deprecated' from bpf.h
while bpftool supported map is displayed as 'cgroup_storage'. The test failure
can be fixed by explicitly replacing 'cgroup_storage_deprecated' with 'cgroup_storage'
in uapi bpf.h map types.

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.
