This series of patches introduced a kernel panic bug. The tests are
based on the linux-next commit [1]. I tried it a few times and found
that if I didn't apply the current patch, the issue wouldn't be
triggered. After applying the current patch, the probability of
triggering the issue was 3/3.
Reproduced steps:
1. git clone https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
2. applied this series of patches
3. compile and install
4. reboot server(A kernel panic occurs at this step)
Thanks for the report. Let me try to reproduce it on my side.
Hi Breno

Is this a physical machine, or, are you using a VM with the virtio change?
Yes, I test it with a physical machine. I didn't used VM， just install
rpm which compiled based on this series patches, then hit kernel pahic
at server rebooting.
Also, I've just sent v3 earlier today, let me know if you have chance to
test it as well, given it fixes the issue raised by Jakub in [1]

I already submitted a job to test v3, the test will be completed
tomorrow and I will update the results promptly.
Best Regards
