From: Xianting Tian <redacted> Cpu stall issue may happen if device is configured with multi queues and large queue depth, so fix it.What does "may happen" imply exactly? was this observed?I didn't met such issue, this patch set just a theoretical fix.
Then I would not recommend adding it at this time, as you just slowed down the kernel for something that no one has reported :( thanks, greg k-h _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
