From 04060db41178c7c244f2c7dcd913e7fd331de915 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Wed, 15 Jan 2020 20:47:37 -0800 Subject: scsi: RDMA/isert: Fix a recently introduced regression related to logout iscsit_close_connection() calls isert_wait_conn(). Due to commit e9d3009cb936 both functions call target_wait_for_sess_cmds() although that last function should be called only once. Fix this by removing the target_wait_for_sess_cmds() call from isert_wait_conn() and by only calling isert_wait_conn() after target_wait_for_sess_cmds(). Fixes: e9d3009cb936 ("scsi: target: iscsi: Wait for all commands to finish before freeing a session").
