      [PATCH] blk: fix tag shrinking (revive real_max_size) · ba025082
      Tejun Heo authored
      My patch in commit fa72b903 incorrectly
      removed blk_queue_tag->real_max_depth.
      
      The original resize implementation was incorrect in the following
      points.
      
       * actual allocation size of tag_index was shorter than real_max_size,
         but assumed to be of the same size, possibly causing memory access
         beyond the allocated area.
       * bits in tag_map between max_deptn and real_max_depth were
         initialized to 1's, making the tags permanently reserved.
      
      In an attempt to fix above two bugs, I had removed allocation optimization
      in init_tag_map and real_max_size.  Tag map/index were allocated and freed
      immediately during resize.
      
      Unfortunately, I wasn't considering that tag map/index can be resized
      dynamically with tags beyond new_depth active.  This led to accessing
      freed area after shrinking tags and led to the following bug reporting
      thread on linux-scsi.
      
         http://marc.theaimsgroup.com/?l=linux-scsi&m=112319898111885&w=2
      
      To fix the problem, I've revived real_max_depth without allocation
      optimization in init_tag_map, and Andrew Vasquez confirmed that the
      problem was fixed.  As Jens is not going to be available for a week, he
      asked me to make sure that this patch reaches you.

      Also, a comment was added to make sure that real_max_size is needed for
      dynamic shrinking.

      [PATCH] blk: light iocontext ops · fb3cc432
      Nick Piggin authored
      
      
      get_io_context needlessly turned off interrupts and checked for racing io
      context creations.  Both of which aren't needed, because the io context can
      only be created while in process context of the current process.
      
      Also, split the function in 2.  A light version, current_io_context does not
      elevate the reference count specifically, but can be used when in process
      context, because the process holds a reference itself.

      [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] fix NMI lockup with CFQ scheduler · 152587de
      authored
      
      
      The current problem seen is that the queue lock is actually in the
      SCSI device structure, so when that structure is freed on device
      release, we go boom if the queue tries to access the lock again.
      
      The fix here is to move the lock from the scsi_device to the queue.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
