Subject: [PATCH 04/11] nptl: Add pthread_attr_setaffinity_np failure test
Date: Wed, 26 May 2021 13:57:21 -0300 [thread overview]
Message-ID: <20210526165728.1772546-5-adhemerval.zanella@linaro.org> (raw)
In-Reply-To: <20210526165728.1772546-1-adhemerval.zanella@linaro.org>
It checks whether an invalid affinity mask does return an error,
similar to what sysdeps/pthread/tst-bad-schedattr.c does for
pthread_attr_setschedparam.
Checked on x86_64-linux-gnu.
