   5 Subject: dlm: replace schedule with cond_resched
   6
   7     This is a one-liner to use cond_resched() rather than schedule()
   8     in the ast delivery loop. It should not be necessary to schedule
   9     every time, so this will save some cpu time while continuing to
  10     allow scheduling when required.
