Quentin Monnet says: ==================== Hi, this set aims at updating the way bpftool versions are numbered. Instead of copying the version from the kernel (given that the sources for the kernel and bpftool are shipped together), align it on libbpf's version number, with a fixed offset (6) to avoid going backwards. Please refer to the description of the second commit for details on the motivations. The patchset also adds the number of the version of libbpf that was used to compile to the output of "bpftool version". Bpftool makes such a heavy usage of libbpf that it makes sense to indicate what version was used to build it. v3: - Compute bpftool's version at compile time, but from the macros exposed by libbpf instead of calling a shell to compute $(BPFTOOL_VERSION) in the Makefile. - Drop the commit which would add a "libbpfversion" target to libbpf's Makefile. This is no longer necessary. - Use libbpf's major, minor versions with jsonw_printf() to avoid offsetting the version string to skip the "v" prefix. - Reword documentation change. v2: - Align on libbpf's version number instead of creating an independent versioning scheme. - Use libbpf_version_string() to retrieve and display libbpf's version. - Re-order patches (1 <-> 2). ==================== Signed-off-by: Andrii Nakryiko <andrii@kernel.org>
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.
