From: Andy Grover Date: Thu, 19 Jan 2012 21:39:11 +0000 (-0800) Subject: scsi: Use struct scsi_lun in fc/fcp.h X-Git-Tag: firefly_0821_release~3680^2~3307^2~56 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=e35fa8c2d0feb977c2f7d14a973b4132483ffef3;p=firefly-linux-kernel-4.4.55.git scsi: Use struct scsi_lun in fc/fcp.h This allows us to use scsilun_to_int without an ugly cast. Fix up places that use scsilun_to_int on fcp->fc_lun accordingly. In fc target, this leaves ft_cmd.lun unused, so remove it.
