Subject: [PATCH 2/2] tests/tcg/linux-test: Check that sigaction can query SIGKILL/SIGSTOP
Date: Tue,  1 Jun 2021 16:56:00 +0200	[thread overview]
Message-ID: <20210601145600.3131040-3-iii@linux.ibm.com> (raw)
In-Reply-To: <20210601145600.3131040-1-iii@linux.ibm.com>

Verify that querying is allowed, but making changes isn't.
