+Subject: [PATCH] fio: remove raw device support
+
+As of Linux kernel commit 603e4922f1c ("remove the raw driver"),
+linux/raw.h is gone, and raw device support no longer exists.
+Because of this, fio can no longer build against the current Linux
+kernel headers.
+
+So, remove raw device support from fio as well.
