Subject: [RFC PATCH 2/7] vfio/pci: Implement match ops
Date: Tue, 04 Feb 2020 16:05:51 -0700	[thread overview]
Message-ID: <158085755166.9445.17279904229413350701.stgit@gimli.home> (raw)
In-Reply-To: <158085337582.9445.17682266437583505502.stgit@gimli.home>

This currently serves the same purpose as the default implementation
but will be expanded for additional functionality.
