Subject: [PATCH] Assemble: mask FAILFAST and WRITEMOSTLY flags when finding
 the most recent device
Git-commit: 563ac108659980b3d1e226fe416254a86656235f
Patch-mainline: mdadm-4.1+
References: jsc#SLE-10078, jsc#SLE-9348

If devices[].i.disk.state has MD_DISK_FAILFAST or MD_DISK_WRITEMOSTLY
flag, it cannot be the most recent device. Both flags should be masked
before checking the state.
