From e3d6f909ed803d92a5ac9b4a2c087e0eae9b90d0 Mon Sep 17 00:00:00 2001 From: Andy Grover Date: Tue, 19 Jul 2011 08:55:10 +0000 Subject: target: Core cleanups from AGrover (round 1) This patch contains the squashed version of a number of cleanups and minor fixes from Andy's initial series (round 1) for target core this past spring. The condensed log looks like: target: use errno values instead of returning -1 for everything target: Rename transport_calc_sg_num to transport_init_task_sg target: Fix leak in error path in transport_init_task_sg target/pscsi: Remove pscsi_get_sh() usage target: Make two runtime checks into WARN_ONs target: Remove hba queue depth and convert to spin_lock_irq usage target: dev->dev_status_queue_obj is unused target: Make struct se_queue_req.cmd type struct se_cmd * target: Remove __transport_get_qr_from_queue() target: Rename se_dev->g_se_dev_list to se_dev_node target: Remove struct se_global target: Simplify scsi mib index table code target: Make dev_queue_obj a member of se_device instead of a pointer target: remove extraneous returns at end of void functions target: Ensure transport_dump_vpd_ident_type returns null-terminated str target: Function pointers don't need to use '&' to be assigned target: Fix comment in __transport_execute_tasks() target: Misc style cleanups target: rename struct pr_reservation_template to pr_reservation target: Remove #defines that just perform indirection target: Inline transport_get_task_from_execute_queue() target: Minor header comment fixes Signed-off-by: Andy Grover Signed-off-by: Nicholas Bellinger --- drivers/target/target_core_pr.c | 364 ++++++++++++++++++++-------------------- 1 file changed, 182 insertions(+), 182 deletions(-) (limited to 'drivers/target/target_core_pr.c') diff --git a/drivers/target/target_core_pr.c b/drivers/target/target_core_pr.c index b662db3a320..27a7525971b 100644 --- a/drivers/target/target_core_pr.c +++ b/drivers/target/target_core_pr.c @@ -105,13 +105,13 @@ static int core_scsi2_reservation_check(struct se_cmd *cmd, u32 *pr_reg_type) } if (dev->dev_reserved_node_acl != sess->se_node_acl) { spin_unlock(&dev->dev_reservation_lock); - return -1; + return -EINVAL; } if (!(dev->dev_flags & DF_SPC2_RESERVATIONS_WITH_ISID)) { spin_unlock(&dev->dev_reservation_lock); return 0; } - ret = (dev->dev_res_bin_isid == sess->sess_bin_isid) ?
