+Subject: [PATCH] libparted: Flush parent device on open (#962611)
+
+Parted probes for filesystems using geometry offsets into the parent
+device, not the partition device itself. This means it may get stale
+information if a partition has just been formatted.
+
+On kernels before 2.6 this will also flush all partition devices. On 2.6
+and newer kernels it will only flush the parent device.
+
+* libparted/arch/linux.c (linux_open): Always call _flush_cache
