Re: [Xen-devel] [PATCH RFC v6 10/11] pvqspinlock, x86: Enable qspinlock PV support for KVM

This should also disable the unfair path.


The unfair lock uses a different jump label and does not require any
special PV ops. There is a separate init function for that.

Yeah, what I mean is that the patches that enable paravirtualization should also take care of decreasing the unfair-lock jump label when paravirtualization is enabled.
