    Merge branch 'for-3.5/core' of git://git.kernel.dk/linux-block · 0d167518
    Linus Torvalds authored
    Merge block/IO core bits from Jens Axboe:
     "This is a bit bigger on the core side than usual, but that is purely
      because we decided to hold off on parts of Tejun's submission on 3.4
      to give it a bit more time to simmer.  As a consequence, it's seen a
      long cycle in for-next.
    
      It contains:
    
       - Bug fix from Dan, wrong locking type.
       - Relax splice gifting restriction from Eric.
       - A ton of updates from Tejun, primarily for blkcg.  This improves
         the code a lot, making the API nicer and cleaner, and also includes
         fixes for how we handle and tie policies and re-activate on
         switches.  The changes also include generic bug fixes.
       - A simple fix from Vivek, along with a fix for doing proper delayed
         allocation of the blkcg stats."
    
    Fix up annoying conflict just due to different merge resolution in
    Documentation/feature-removal-schedule.txt
