Which kernel version is this patch based on?
If it's a fix for a patch that hasn't landed yet, please indicate this.
A "Fixes: ..." tag should be added to this patch as well.
I looked at linux.git/master commit f69d02e37a85645aa90d18cacfff36dba370f797 and see this:
static int __init vhost_scsi_init(void)
{
int ret = -ENOMEM;
pr_debug("TCM_VHOST fabric module %s on %s/%s"
" on "UTS_RELEASE"\n", VHOST_SCSI_VERSION, utsname()->sysname,
utsname()->machine);
/*
* Use our own dedicated workqueue for submitting I/O into
* target core to avoid contention within system_wq.
*/
vhost_scsi_workqueue = alloc_workqueue("vhost_scsi", 0, 0);
if (!vhost_scsi_workqueue)
goto out;
We need ret's initialization value here ^
ret = vhost_scsi_register();
if (ret < 0)
goto out_destroy_workqueue;
ret = target_register_template(&vhost_scsi_ops);
if (ret < 0)
goto out_vhost_scsi_deregister;
return 0;
out_vhost_scsi_deregister:
vhost_scsi_deregister();
out_destroy_workqueue:
destroy_workqueue(vhost_scsi_workqueue);
out:
return ret;
};
