Subject: [PATCH] selftests/mqueue: fix 5 warnings about signed/unsigned mismatches
Date: Sun, 5 May 2024 15:13:59 -0700 [thread overview]
Message-ID: <20240505221359.65258-1-jhubbard@nvidia.com> (raw)
When building with clang, via:
make LLVM=1 -C tools/testing/selftest
...clang warns about several cases of using a signed integer for the
priority argument to mq_receive(3), which expects an unsigned int.
Fix this by declaring the type as unsigned int in all cases.
