From e514385be2b355c1f3fc6385a98a6a0fc04235ae Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Tue, 9 Aug 2005 11:55:36 -0500 Subject: [SCSI] fix sense buffer length handling problem The new bio code was incorrectly converted from stack allocated to kmalloc'd buffer handling. There are two places where it incorrectly uses sizeof(*sense) to get the size of the sense buffer. This actually produces one, so no sense data was ever getting back, causing failure in things like disk spin up.
