+
+329dfc28debb disallows the creation of raid0 with layouts for 0.9
+metadata. This test confirms the new behavior.

+Subject: [PATCH] tests/00readonly: Run udevadm settle before setting ro
+
+In some recent kernel versions, 00readonly fails with:
+
+  mdadm: failed to set readonly for /dev/md0: Device or resource busy
+  ERROR: array is not read-only!
+
+This was traced down to a race condition with udev holding a reference
+to the block device at the same time as trying to set it read only.
+
+To fix this, call udevadm settle before setting the array read only.

+'04update-metadata' test fails with error, "specifying chunk size is

+
+Some of the test cases fail because raid0 creation fails with the error,
+"0.90 metadata does not support layouts for RAID0" added by commit,
