Subject: [REVIEW][PATCH 4/4] signal/arm/kvm: Use send_sig_mceerr
Date: Mon, 24 Sep 2018 14:11:28 +0200 [thread overview]
Message-ID: <20180924121128.5983-4-ebiederm@xmission.com> (raw)
In-Reply-To: <87pnx32j2p.fsf@xmission.com>
This simplifies the code making it clearer what is going on, and
making the siginfo generation easier to maintain.
