3.0-stable review patch. If anyone has any objections, please let us know.
------------------
From: "Stephen M. Cameron" <scame...@beardog.cce.hp.com>
commit fec62c368b9c8b05d5124ca6c3b8336b537f26f3 upstream.
Most smartarrays tolerate it, but a few new ones don't.
Without this change some newer Smart Arrays will lock up
and i/o will grind to a halt.
