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. Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
