Subject: [PATCH V2 09/20] qla2xxx: Set host can_queue value based on available resources.
Date: Mon, 16 Dec 2013 22:28:32 -0500 [thread overview]
Message-ID: <1387250923-1041-10-git-send-email-saurav.kashyap@qlogic.com> (raw)
In-Reply-To: <1387250923-1041-1-git-send-email-saurav.kashyap@qlogic.com>
From: Chad Dupuis <chad.dupuis@qlogic.com>
Tell the mid-layer that number of commands we can queue is the available
resources we have minus a small amount for internal commands.
