Subject: [PATCH 3/7] iscsi-target: Clear map_sg usage for non ISTATE_SEND_DATAIN ops
Date: Fri, 3 Jun 2011 18:18:14 -0700 [thread overview]
Message-ID: <1307150298-23921-4-git-send-email-nab@linux-iscsi.org> (raw)
In-Reply-To: <1307150298-23921-1-git-send-email-nab@linux-iscsi.org>
From: Nicholas Bellinger <nab@linux-iscsi.org>
This patch fixes a bug in iscsi_target_tx_thread() where 'map_sg' was not
being cleared after ISTATE_SEND_DATAIN and causing iscsit_fe_sendpage_sg()
to be called for non ISTATE_SEND_DATAIN + non ISCSI_OP_SCSI_CMD payloads.
