Subject: [PATCH v3 2/7] block: introduce API to register stream information with block layer
Date: Fri, 29 Mar 2019 13:23:47 +0530	[thread overview]
Message-ID: <1553846032-4451-3-git-send-email-joshi.k@samsung.com> (raw)
In-Reply-To: <1553846032-4451-1-git-send-email-joshi.k@samsung.com>

This associates stream limit (count of streams exposed by driver) with
request queue.
