Subject: [PATCH 1/2] linux-user: Let sigaction query SIGKILL/SIGSTOP
Date: Tue, 1 Jun 2021 16:55:59 +0200 [thread overview]
Message-ID: <20210601145600.3131040-2-iii@linux.ibm.com> (raw)
In-Reply-To: <20210601145600.3131040-1-iii@linux.ibm.com>
The kernel allows doing this, so let's allow this in qemu as well.
Valgrind relies on this.
