Subject: [SCSI] scsi_dh: Initialize path state to be passive when path is not owned
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5a36756b8b3d7178d9c101d1e2a7a83fd7b17706;p=openwrt%2Fstaging%2Fblogic.git

[SCSI] scsi_dh: Initialize path state to be passive when path is not owned

Set the path state to be passive when we learn that the controller does
not own the path to the LUN.

This will avoid sending even a single i/o thru the passive path at the
probe time.
