An older GCC compiler complains:
kernel/bpf/verifier.c: In function 'bpf_check':
kernel/bpf/verifier.c:4***:13: error: 'prev_offset' may be used uninitialized
in this function [-Werror=maybe-uninitialized]
} else if (krecord[i].insn_offset <= prev_offset) {
^
kernel/bpf/verifier.c:4***:38: note: 'prev_offset' was declared here
u32 i, nfuncs, urec_size, min_size, prev_offset;
Although the compiler is wrong here, the patch makes sure
that prev_offset is always initialized, just to silence the warning.
v2: fix a spelling error in the commit message.

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.
