[PATCH] SCSI core: display sdev->scsi_level correctly

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch (as833) fixes the "SCSI revision" output for
/proc/scsi/scsi.  If the scsi_level value is 0 (UNKNOWN), we want it
to show up as "0", not "ffffffff".

James, this is a resubmission.  Apparently the original message get lost 
in the woodwork.
