[PATCH v8 0/6] Implement qspinlock/pv-qspinlock on ppc
Hi All,
this is the fairlock patchset. You can apply them and build successfully.
patches are based on linux-next
qspinlock can avoid waiter starved issue. It has about the same speed in
single-thread and it can be much faster in high contention situations
especially when the spinlock is embedded within the data structure to be
protected.
v7 -> v8:
add one patch to drop a function call
