thanks boqun and Peter's suggestion.
This patch set aims to fix lock holder preemption issues.
So I really like the concept, but I would also really like to see
support for more hypervisors included before we can move forward with
this.
Please consider s390 and (x86/arm) KVM. Once we have a few, more can
follow later, but I think its important to not only have PPC support for
this.
hi, Peter
right, we need consider more arches.
I will try to work out a RFC patch on x86 anyway. There are already some discussions of the solution on x86 :)
thanks
