Subject: [PATCH v2 4/5] HID: hv: Remove dependencies on PAGE_SIZE for ring buffer
Date: Thu, 6 Jun 2019 08:07:58 +0000	[thread overview]
Message-ID: <0e9385a241dc7c26445eb7e104d08e2e2c5d30de.1559807514.git.m.maya.nakamura@gmail.com> (raw)
In-Reply-To: <cover.1559807514.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.
