From c9eeb248f3b44939532a9716bc06413383aa5d63 Mon Sep 17 00:00:00 2001 From: Boaz Harrosh Date: Wed, 24 Sep 2008 12:00:22 +0300 Subject: [PATCH] [SCSI] qlogicpti: fix sg list traversal error in continuation entries The current sg list traversal logic for the continuation entries doesn't advance the list pointer once all seven slots are used, so the next continuation entry (if there is one) wrongly begins again at the start of the sg list. Fix by advancing the sg pointer after the for_each_sg().
