Subject: [PATCH v3 4/5] HID: hv: Remove dependencies on PAGE_SIZE for ring buffer
Date: Tue, 18 Jun 2019 06:15:55 +0000 [thread overview]
Message-ID: <8e244063840664b7d54d545e73e9c6d83f7913e6.1560837096.git.m.maya.nakamura@gmail.com> (raw)
In-Reply-To: <cover.1560837096.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.
