Subject: [SCSI] libfc: use DID_TRANSPORT_DISRUPTED while lport not ready
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=75eee7252466342e0dfa6675106bcd3955090f67;p=deliverable%2Flinux.git

[SCSI] libfc: use DID_TRANSPORT_DISRUPTED while lport not ready

This is per Mile Christie feedback since in this case IO
could get retried for tape devices and therefore DID_REQUEUE
cannot be used, more details in this thread.
