      [PATCH] more io scheduler updates · 156889a0
      Jens Axboe authored
      Small problem, we must of course also remember to take into account
      where the last service point was (or will be).
      
      deadline_get_last_sector() either returns the last offset serviced, or
      the last one that will be (back of dispatch queue).
      
      Otherwise the insert-at-head can be very unfair.

      [PATCH] MODULE_LICENSE for i82092 pcmcia. · 3b1bbff1
      Geoffrey Lee authored
      It appears that during the MODULE_LICENSE merge for pcmcia i82092 was
      missed.
      
      Here is a trivial patch to correct this.

      [PATCH] io scheduler update · 33fb2ab5
      Jens Axboe authored
      This fixes a problem with the deadline io scheduler, if the correct
      insertion point is at the front of the list.  This is something that we
      never have gotten right in 2.4 either.
      
      The problem is that the elevator merge function has to return a pointer
      to a struct request, and for front insert we really have to return the
      head of the list which cannot be expressed as a request of course.
      
      The real issue is that the elevator_merge function actually performs two
      functions - it scans for a merge, and if it can't find any, it selects
      and insertion point.  It's done this way for efficiency reasons, even if
      the design isn't all that clean.
      
      So we change the io scheduler merge functions to get passed a pointer to
      a list_head pointer instead.  This works for both inserts and merges.
      In addition, deadline checks if it really should insert at the very
      front.
      
      Also don't pass in request to elv_try_last_merge(), the very name of the
      function suggests that it's q->last_merge that we are interested in.
