Both bpf_strtol() and bpf_strtoul() helpers passed a temporary "long long"
respectively "unsigned long long" to __bpf_strtoll() / __bpf_strtoull().
Later, the result was checked for truncation via _res != ({unsigned,} long)_res
as the destination buffer for the BPF helpers was of type {unsigned,} long
which is 32bit on 32bit architectures.
Given the latter was a bug in the helper signatures where the destination buffer
got adjusted to {s,u}64, the truncation check can now be removed.

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 reStructuredText 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.
