From: Mike Christie Date: Fri, 24 Jun 2011 20:11:55 +0000 (-0500) Subject: libiscsi_tcp: fix LLD data allocation X-Git-Tag: v3.0.5~41 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6d901cfa36fbf9682aa467cafacb765baa1c10af;p=karo-tx-linux.git libiscsi_tcp: fix LLD data allocation commit 74dcd0ec735ba9c5bef254b2f6e53068cf3f9ff0 upstream. Have libiscsi_tcp have upper layers allocate the LLD data along with the iscsi_cls_conn struct, so it is refcounted.
