Subject: [PATCH 5/6] HID: hv: Remove dependencies on PAGE_SIZE for ring buffer
Date: Fri, 5 Apr 2019 01:19:18 +0000	[thread overview]
Message-ID: <4d5599a835c1ce37b5def62543ea9c9fe3f30329.1554426040.git.m.maya.nakamura@gmail.com> (raw)
In-Reply-To: <cover.1554426039.git.m.maya.nakamura@gmail.com>

Define the ring buffer size as a constant expression because it should
not depend on the guest page size.
