From: Steffen Maier Date: Thu, 17 May 2018 17:15:02 +0000 (+0200) Subject: scsi: zfcp: explicitly support initiator in scsi_host_template X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b24bf22d72c75c4e32e3520041ccdf7c9a2d9e5a;p=openwrt%2Fstaging%2Fblogic.git scsi: zfcp: explicitly support initiator in scsi_host_template While the default did already correctly print "Initiator" let's make it explicit and convert zfcp to the feature. $ cat /sys/class/scsi_host/host0/supported_mode Initiator $ cat /sys/class/scsi_host/host0/active_mode Initiator The default worked, because not setting the field has it initialized to zero == MODE_UNKNOWN. scsi_host_alloc() sets shost->active_mode = MODE_INITIATOR in this case. The sysfs accessor function show_shost_supported_mode() assumes MODE_INITIATOR in this case. This default behavior was introduced with v2.6.24 commit 7a39ac3f25be ("[SCSI] make supported_mode default to initiator."). The feature flag was introduced with v2.6.24 commit 5dc2b89e1242 ("[SCSI] add supported_mode and active_mode attributes to the host"). So there was no release where zfcp would have shown "unknown".
