From afe92323f9df4a2c4a093cd3f2a3f82800498596 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sun, 3 May 2015 08:54:42 +0200 Subject: target: remove ->put_session method The only instance of ->put_session is in qla2xxx, and was added by commit aaf68b ("tcm_qla2xxx: Convert to TFO->put_session() usage") with the following description: This patch converts tcm_qla2xxx code to use an internal kref_put() for se_session->sess_kref in order to ensure that qla_hw_data->hardware_lock can be held while calling qlt_unreg_sess() for the final put. But these day we're already holding the hardware lock over qlt_unreg_sess in the ->close_session callback, so we're fine without this method.
