    gfs2: use workqueue instead of slow-work · 6ecd7c2d
    Tejun Heo authored
    Workqueue can now handle high concurrency.  Convert gfs to use
    workqueue instead of slow-work.
    
    * Steven pointed out that recovery path might be run from allocation
      path and thus requires forward progress guarantee without memory
      allocation.  Create and use gfs_recovery_wq with rescuer.  Please
      note that forward progress wasn't guaranteed with slow-work.
    
    * Updated to use non-reentrant workqueue.
