Subject: [PATCH 06/25] scsi: hisi_sas: add slot init code
Date: Mon, 12 Oct 2015 23:20:18 +0800 [thread overview]
Message-ID: <1444663237-238302-7-git-send-email-john.garry@huawei.com> (raw)
In-Reply-To: <1444663237-238302-1-git-send-email-john.garry-hv44wF8Li93QT0dZR+AlfA@public.gmane.org>
Add functionality to init slot indexing.
Slot indexing is for the host to track which slots
(or tags) are free and which are used.
