In linux kernel since version 2.6.30 (release Date: 2009-06-09)
Paravirtualized spinlocks allow a pvops backend to replace the
spinlock implementation with something virtualization-friendly
(for example, block the virtual CPU rather than spinning).
It has a minimal impact on native kernels and gives a nice performance
benefit on paravirtualized KVM / Xen kernels.
If you are unsure how to answer this question, answer Y.
