Subject: [PATCH v4 5/5] Input: hv: Remove dependencies on PAGE_SIZE for ring buffer
Date: Fri, 12 Jul 2019 08:30:27 +0000 [thread overview]
Message-ID: <5af419d636506d9d87ab7d2650fa800ead91a29a.1562916939.git.m.maya.nakamura@gmail.com> (raw)
In-Reply-To: <cover.1562916939.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.
