title: Scheduling Mechanism in Linux Kernel 3.0+
body: <p>Which Scheduling Mechanism is used with Linux Kernel (3.0+) by default, I guess Premptive Scheduling ?
  <br>Can we select some other mechanism like Deadline First or Round Robin while building (from the menuconfig) ? <br>And In Round-Robin Mechanism, how time slice is allocated and used in Kernel ? (I mean Is the time slice calculated on run-time ?)</p>
