+Subject: [PATCH] snappy: Autospec creation for version 1.1.9
+
+This patch addresses an issue with Ceph
+https://tracker.ceph.com/issues/53060. There have been multiple patches
+to upstream snappy, but they have all been rejected and the reasoning
+has always been that snappy would like to be consistent in their build
+flags with chrome as mentioned at
+https://github.com/google/snappy/pull/144#issuecomment-968371042
