      [PATCH] Update cfq io scheduler to time sliced design · 22e2c507
      Jens Axboe authored
      
      
      This updates the CFQ io scheduler to the new time sliced design (cfq
      v3).  It provides full process fairness, while giving excellent
      aggregate system throughput even for many competing processes.  It
      supports io priorities, either inherited from the cpu nice value or set
      directly with the ioprio_get/set syscalls.  The latter closely mimic
      set/getpriority.
      
      This import is based on my latest from -mm.

      [PATCH] Cleanup patch for process freezing · 3e1d1d28
      Christoph Lameter authored
      
      
      1. Establish a simple API for process freezing defined in linux/include/sched.h:
      
         frozen(process)		Check for frozen process
         freezing(process)		Check if a process is being frozen
         freeze(process)		Tell a process to freeze (go to refrigerator)
         thaw_process(process)	Restart process
         frozen_process(process)	Process is frozen now
      
      2. Remove all references to PF_FREEZE and PF_FROZEN from all
         kernel sources except sched.h
      
      3. Fix numerous locations where try_to_freeze is manually done by a driver
      
      4. Remove the argument that is no longer necessary from two function calls.
      
      5. Some whitespace cleanup
      
      6. Clear potential race in refrigerator (provides an open window of PF_FREEZE
         cleared before setting PF_FROZEN, recalc_sigpending does not check
         PF_FROZEN).
      
      This patch does not address the problem of freeze_processes() violating the rule
      that a task may only modify its own flags by setting PF_FREEZE. This is not clean
      in an SMP environment. freeze(process) is therefore not SMP safe!
