When the user scans the devices through 'scan' sysfs using below command then the user will observe duplicate device entries in lsscsi command output. echo "- - -" > /sys/class/scsi_host/host0/scan
Fix is to set the shost's max_channel to zero.

Please tag this based on a release of Linus's, or better yet, provide a "Fixes:" commit so that the stable people know exactly where to backport it to.
As this is, we do not take patches only for stable kernels...
thanks,

Thanks, Shall I resend the patch with proper "Fixes:" commit ID.

This fix applies for the mainline kernel as well.
Thanks, Sreekanth

Yes please.

That's good, as that is the only way to get patches accepted :)
