+Subject: [PATCH] ephyr,xwayland: Use the proper private key for cursor
+
+The cursor in DIX is actually split in two parts, the cursor itself and
+the cursor bits, each with their own devPrivates.
+
+The cursor itself includes the cursor bits, meaning that the cursor bits
+devPrivates in within structure of the cursor.
+
+Both Xephyr and Xwayland were using the private key for the cursor bits
+to store the data for the cursor, and when using XSELINUX which comes
+with its own special devPrivates, the data stored in that cursor bits'
+devPrivates would interfere with the XSELINUX devPrivates data and the
+SELINUX security ID would point to some other unrelated data, causing a
+crash in the XSELINUX code when trying to (re)use the security ID.
