[PATCH][RFC] kill scsi_dump_status

[Christoph Hellwig <hch@lst.de>]

Is someone still using the echo dump > /proc/scsi/scsi feature?  I think
we should kill it as we're getting much nicer output from sysfs these
days..

- * Function:    scsi_dump_status
- *
- * Purpose:     Brain dump of scsi system, used for problem solving.
- *
- * Arguments:   level - used to indicate level of detail.
- *
- * Notes:       The level isn't used at all yet, but we need to find some
- *		way of sensibly logging varying degrees of information.
- *		A quick one-line display of each command, plus the status
- *		would be most useful.
- *
- *              This does depend upon CONFIG_SCSI_LOGGING - I do want some
- *		way of turning it all off if the user wants a lean and mean
- *		kernel.  It would probably also be useful to allow the user
- *		to specify one single host to be dumped.  A second argument
- *		to the function would be useful for that purpose.
- *
- *              FIXME - some formatting of the output into tables would be
- *		        very handy.
