+Subject: [PATCH] greeter: disable qml disk cache
+
+The cache currently runs risk of getting corrupted and breaking the lock
+screen until the cache hash changes or the cache file gets removed by
+the user. Since we don't necessarily need a cache here let's just
+disable it for the time being in the interest of greater fault
+tolerance.
+
+BUG: 471952
+(cherry picked from commit d1640daa360943f86196e323c4a76bde57566150)
