Subject: [PATCH/RFC 08/10] iommu/ipmmu-vmsa: Break out domain allocation code
Date: Tue, 15 Dec 2015 13:06:23 +0000	[thread overview]
Message-ID: <20151215130623.13535.43116.sendpatchset@little-apple> (raw)
In-Reply-To: <20151215130508.13535.26186.sendpatchset@little-apple>

From: Magnus Damm <damm+renesas@opensource.se>

Break out the domain allocation code into a separate function.
This is preparation for future code sharing.
