+ "prefer pipe2() to pipe() because pipe2() allows O_CLOEXEC",
the message doesn't seem to explain the reason, especially to the people who are not familiar with the `pipe` API, maybe `prefer pipe2() to pipe() to avoid file descriptor leakage` is clearer?
Ah, it looks like you are following the existing `CloexecCreatCheck` check, no need to do it in this patch.
Comment at: clang-tools-extra/test/clang-tidy/android-cloexec-pipe.cpp:17
+ // CHECK-MESSAGES-NOT: warning:
nit: no need to do it explicitly, if a warning is shown unexpectedly, the test will fail.
