Subject: [PATCH v2 03/11] selftests/mm: fix "warning: expression which evaluates to zero..." in mlock2-tests.c
Date: Fri, 2 Jun 2023 19:15:50 -0700 [thread overview]
Message-ID: <20230603021558.95299-4-jhubbard@nvidia.com> (raw)
In-Reply-To: <20230603021558.95299-1-jhubbard@nvidia.com>
The stop variable is a char*, and the code was assigning a char value to
it. This was generating a warning when compiling with clang.
However, as both David and Peter pointed out, stop is not even used
after the problematic assignment to a char type. So just delete that
line entirely.
