If anyone has any objections, please let me know. ------------------ From: NeilBrown commit 58ebb34c49fcfcaa029e4b1c1453d92583900f9a upstream. Create_stripe_zones returns an error slightly differently to raid0_run and to raid0_takeover_*. The error returned used by the second was wrong and an error would result in mddev->private being set to NULL and sooner or later a crash. So never return NULL, return ERR_PTR(err), not NULL from create_stripe_zones. This bug has been present since 2.6.35 so the fix is suitable for any kernel since then.
