From: "Joel Fernandes (Google)" <[email protected]> Hi, Here is test code and kselftest for testing the preemptoff and irqsoff tracers. I am posting it separately just for early feedback since its the first time I'm writing a kselftest.
I am planning to include these tests in the next series posting of "Centralize and unify usage of preempt/irq tracepoints" [1] By the way, other than these I have also completed testing with Ingo's locking API test suite for [1]. I will include these and other results in the v7 posting of [1].
