From a3bec5c5aea0da263111c4d8f8eabc1f8560d7bf Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Wed, 17 Oct 2007 19:33:05 +0200 Subject: [PATCH] Revert "[SCSI] Remove full sg table memset()" A bit too eager - we definitely need to clear the sg table initially, so that we don't accidentally have ->page & 0x01 true and think that is a chain pointer.
