Commit\nb39f35ebe86d (\"md: don't quiesce in mddev_suspend()\") removed that\nquiesce(mddev, 0) call, so the pre-set now sticks.\n\nsetup_conf() already zero-initializes the new r1conf via kzalloc, so\njust don't set array_frozen here.\n\nSame class of bug as commit 892da88d1cd9 (\"md/raid10: fix a\n'conf->barrier' leakage in raid10_takeover()\"), also triggered by\nb39f35ebe86d."
