From 2697478903d0ad8bdbf868b1346ae4b891662bb1 Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Thu, 13 Dec 2007 12:43:29 -0600 Subject: [SCSI] libiscsi: fix shutdown We were using the device delete sysfs file to remove each device then logout. Now in 2.6.21 this will not work because the sysfs delete file returns immediately and does not wait for the device removal to complete. This causes a hang if a cache sync is needed during shutdown. Before .21, that approach had other problems, so this patch fixes the shutdown code so that we remove the target and unbind the session before logging out and shut down the session Signed-off-by: Mike Christie Signed-off-by: James Bottomley --- drivers/scsi/qla4xxx/ql4_os.c | 7 ++----- 1 file changed, 2 insertions(+), 5 deletions(-) (limited to 'drivers/scsi/qla4xxx/ql4_os.c') diff --git a/drivers/scsi/qla4xxx/ql4_os.c b/drivers/scsi/qla4xxx/ql4_os.c index 89460d27c68..f55b9f7d939 100644 --- a/drivers/scsi/qla4xxx/ql4_os.c +++ b/drivers/scsi/qla4xxx/ql4_os.c @@ -298,8 +298,7 @@ void qla4xxx_destroy_sess(struct ddb_entry *ddb_entry) return; if (ddb_entry->conn) { - iscsi_if_destroy_session_done(ddb_entry->conn); - iscsi_destroy_conn(ddb_entry->conn); + atomic_set(&ddb_entry->state, DDB_STATE_DEAD); iscsi_remove_session(ddb_entry->sess); } iscsi_free_session(ddb_entry->sess); @@ -309,6 +308,7 @@ int qla4xxx_add_sess(struct ddb_entry *ddb_entry) { int err; + ddb_entry->sess->recovery_tmo = ddb_entry->ha->port_down_retry_count; err = iscsi_add_session(ddb_entry->sess, ddb_entry->fw_ddb_index); if (err) { DEBUG2(printk(KERN_ERR "Could not add session.\n")); @@ -321,9 +321,6 @@ int qla4xxx_add_sess(struct ddb_entry *ddb_entry) DEBUG2(printk(KERN_ERR "Could not add connection.\n")); return -ENOMEM; } - - ddb_entry->sess->recovery_tmo = ddb_entry->ha->port_down_retry_count; - iscsi_if_create_session_done(ddb_entry->conn); return 0; } -- cgit v1.2.3
