Subject: [PATCH 4/4] scsi: hisi_sas: Use libsas internal abort support
Date:   Thu, 3 Mar 2022 20:18:50 +0800
Message-ID: <1646309930-138960-5-git-send-email-john.garry@huawei.com>
In-Reply-To: <1646309930-138960-1-git-send-email-john.garry@huawei.com>
References: <1646309930-138960-1-git-send-email-john.garry@huawei.com>
MIME-Version: 1.0
Content-Type: text/plain
Precedence: bulk

Use the common libsas internal abort functionality.

In addition, this driver has special handling for internal abort timeouts -
specifically whether to reset the controller in that instance, so extend
the API for that.

Timeout is now increased to 20 * Hz from 6 * Hz.

We also retry for failure now, but this should not make a difference.
