Avi, does this patch help the case as you mentioned above, where kvm module is loaded but no virtual machines are present ? Why we have to walk the empty while holding the spinlock?
It might help marginally, but rather than defending the patch, it might be more useful to try finding a solution to the problem Mike and Eric are triggering. How can we prevent the code from taking the lock and throwing out EPT/NPT pages when there is no real need to, and they will be faulted back in soon anyway? -- All rights reversed -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
