OK, but just trying to shoot the messenger isn't at all helpful in this
case. We use the 0day test suite as one of our primary bulwarks
against submission bugs and it clearly identified your commit as the
first bad one. Thus either we need your code fixed or we need the test
fixed; can you work with the 0day people to root cause this? Jan can
probably help, just in case it's a patch interaction problem.
Thanks,
James

OK, but just trying to shoot the messenger isn't at all helpful in this
case. We use the 0day test suite as one of our primary bulwarks
against submission bugs and it clearly identified your commit as the
first bad one. Thus either we need your code fixed or we need the test
fixed; can you work with the 0day people to root cause this? Jan can
probably help, just in case it's a patch interaction problem.
Thanks,

error occurs a few lines up in the log and it took me a while to
notice.
Back to wrestling with the reproduction instructions...

RIght, I'm not shooting the messenger just pointing out that the real
error occurs a few lines up in the log and it took me a while to
notice.
Back to wrestling with the reproduction instructions...

Sorry, I'm using gmail, but I'll switch to attaching the logs.
So with help from Xiaolong I was able to reproduce this, and it does
not appear to be a regression. We simply change the failure output of
an existing bug. Attached is a log of the same test on v4.10-rc7 (i.e.
without the recent block/scsi fixes), and it shows sda being
registered twice.
"[ 6.647077] kobject (d5078ca4): tried to init an initialized
object, something is seriously wrong."
The change that "scsi, block: fix duplicate bdi name registration
crashes" makes is to properly try to register sdb since the sda devt
is still alive. However that's not a fix because we've managed to call
blk_register_queue() twice on the same queue.

Sorry, I'm using gmail, but I'll switch to attaching the logs.
So with help from Xiaolong I was able to reproduce this, and it does
not appear to be a regression. We simply change the failure output of
an existing bug. Attached is a log of the same test on v4.10-rc7 (i.e.
without the recent block/scsi fixes), and it shows sda being
registered twice.
"[ 6.647077] kobject (d5078ca4): tried to init an initialized
object, something is seriously wrong."
The change that "scsi, block: fix duplicate bdi name registration
crashes" makes is to properly try to register sdb since the sda devt
is still alive. However that's not a fix because we've managed to call
blk_register_queue() twice on the same queue.

So sda is probed twice, and hilarity ensues when we try to register it
twice. I can't reproduce this, using scsi_debug and with scsi_async
enabled.
This is running linux-next? What's your .config?

The original failure report is here:
http://marc.info/?l=linux-kernel&m=148619222300774&w=2
...but it reproduces on current mainline with the same config. I
haven't spotted what makes scsi_debug behave like this.

Looking at the config, it's a static debug with report luns enabled.
Is it as simple as the fact that we probe lun 0 manually to see if the
target exists, but then we don't account for the fact that we already
did this, so if it turns up again in the report lun scan, we'll probe
it again leading to a double add. If that theory is correct, this may
be the fix (compile tested only).

Looking at the config, it's a static debug with report luns enabled.
Is it as simple as the fact that we probe lun 0 manually to see if the
target exists, but then we don't account for the fact that we already
did this, so if it turns up again in the report lun scan, we'll probe
it again leading to a double add. If that theory is correct, this may
be the fix (compile tested only).

I gave this a shot on top of linux-next, but still hit the failure.

Actually, when you look closely, it's not a double add; it's an
add/remove/add. You can see this from
[ 6.488377] sd 0:0:0:0: [sda] Synchronizing SCSI cache
That's from sd_shutdown() as the driver is removing. It looks like
something with the config caused the built in SCSI debug to do this
(not sure why), but since the stack trace is in block, I think the bug
is in the remove path: something didn't release the mq object
correctly.

Hmm, I believe it was caused by job-script saved as dos format, I can reproduce
it when I downloaded it through outlook attachment.
Try `dos2unix job-script` before "lkp qemu" to see whether it works.
