Subject: [PATCH] iscsi-target: Expose per endpoint dynamic_sessions attribute
This patch exposes a new ../iscsi/$IQN/$TPGT/dynamic_sessions attribute
to dump the currently active sessions by iSCSI InitiatorName 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.
