Subject: [PATCH] SAM-3 status codes
Date: Thu, 23 Jan 2003 10:10:18 +1100 [thread overview]
Message-ID: <3E2F24DA.50206@torque.net> (raw)
[-- Attachment #1: Type: text/plain, Size: 517 bytes --]
The perverse CHECK_CONDITION in include/scsi/scsi.h seems
to have struck again (see "Can't burn DVD under 2.5.59 with
ide-cd" thread on the linux kernel list). Most users of
CHECK_CONDITION found out to their surprise that it is
shifted 1 bit (right) from those values found in the
standards.
The attachment marks the orginal list of SCSI status codes
as deprecated and supplies defines taken from the most
recent SAM-3 draft.
The patch is against 2.5.59 but may also be suitable for
the lk 2.4 tree.
