Subject: [PATCH v2 5/6] selftests/powerpc: Add wrapper for gettid
Date: Mon, 27 Jul 2020 09:30:39 +0530 [thread overview]
Message-ID: <8ca3b0eeda989707815d1cf337cc33f090408965.1595821792.git.sandipan@linux.ibm.com> (raw)
In-Reply-To: <cover.1595821792.git.sandipan@linux.ibm.com>
The gettid() syscall wrapper was first introduced in
glibc 2.30. This adds a wrapper for use in distros
running older versions.
