From 8467b96c035a45418c5db2619f396b7131b4efa8 Mon Sep 17 00:00:00 2001 From: Yi Zou Date: Mon, 16 May 2011 16:45:57 -0700 Subject: [PATCH] [SCSI] libfc: do not immediately retry the cmd when seq_send fails in fc_fcp_send_data Currently, when seq_send() fails in fc_fcp_send_data(), fc_fcp_retry_cmd() would complete this failed I/O directly and let scsi-ml retry. However, target side is not notified which may hang the target. Instead, we should just bail out from from fc_fcp_send_data and let scsi-ml times it out and aborts this I/O instead.
