From beb40487508290f5d6565598c60a3f44261beef2 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sat, 10 Jun 2006 18:01:03 +0200 Subject: [SCSI] remove scsi_request infrastructure With Achim patch the last user (gdth) is switched away from scsi_request so we an kill it now. Also disables some code in i2o_scsi that was broken since the sg driver stopped using scsi_requests.
