Using %ld for printing out value of ptrdiff_t type is not portable between 32-bit and 64-bit archs. This is causing compilation errors for libbpf on 32-bit platform (discovered as part of an effort to integrate libbpf into systemd ([0])). Proper formatter is %td, which is used in this patch. v2->v1: - add Reported-by - provide more context on how this issue was discovered [0] https://github.com/systemd/systemd/pull/12151 Reported-by: Evgeny Vereshchagin <evvers@ya.ru> Cc: Daniel Borkmann <daniel@iogearbox.net> Cc: Alexei Starovoitov <ast@fb.com> Cc: Yonghong Song <yhs@fb.com> Signed-off-by: Andrii Nakryiko <andriin@fb.com> Acked-by: Song Liu <songliubraving@fb.com> Signed-off-by: Alexei Starovoitov <ast@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.
