Hi Viresh,

I'm not sure how the simple commit will impact will-it-scale/pwrite2
throughput. Just in case you can see more clues.

git://git.linaro.org/people/vireshk/linux tick/ONESHOT-STOPPED
commit d5a085970b0b88b8c82303d2c45f09c9427fd02a ("clockevents: x86: add support for ONESHOT_STOPPED mode")

test case: nhm4/will-it-scale/pwrite2
