--- Comment #4 from Yijing Wang <wangyijing@huawei.com> ---
I also found the same issue when remove my disk in my platform, I think the
code logic is incorrect, this call trace would appear every disk remove. I
found Dan Williams posted a fix patch, but it was not merged to kernel.
https://www.mail-archive.com/linux-scsi@vger.kernel.org/msg39187.html
Following is my call trace:
