Subject: Merge branch 'rcu/refscale' into next
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a50413848f1cf66fa7cb464271f9f81f78808121;p=thirdparty%2Flinux.git

Merge branch 'rcu/refscale' into next

Add performance testing for common context synchronizations
(Preemption, IRQ, Softirq) and per-cpu increments. Those are
relevant comparisons against SRCU-fast read side APIs, especially
as they are planned to synchronize further tracing fast-path code.
