Subject: [RFC PATCH for 4.16 21/21] rseq: selftests: Provide Makefile, scripts, gitignore
Date: Thu, 14 Dec 2017 11:14:03 -0500 [thread overview]
Message-ID: <20171214161403.30643-22-mathieu.desnoyers@efficios.com> (raw)
In-Reply-To: <20171214161403.30643-1-mathieu.desnoyers@efficios.com>
A run_param_test.sh script runs many variants of the parametrizable
tests.
Wire up the rseq Makefile, add directory entry into MAINTAINERS file.
