Subject: [PATCH] tcm_qla2xxx: Expose per endpoint dynamic_sessions attribute
This patch exposes a new ../qla2xxx*/$WWPN/$TPGT/dynamic_sessions
attribute to dump the currently active sessions by FC initiator WWPN
that have been created with dynamically generated se_node_acls.
This information is useful so that user-space can optionally perform
dynamic -> explicit NodeACL conversion based on $INITIATOR_WWPN.
