      Btrfs: avoid sleeping in verify_parent_transid while atomic · b9fab919
      Chris Mason authored
      verify_parent_transid needs to lock the extent range to make
      sure no IO is underway, and so it can safely clear the
      uptodate bits if our checks fail.
      
      But, a few callers are using it with spinlocks held.  Most
      of the time, the generation numbers are going to match, and
      we don't want to switch to a blocking lock just for the error
      case.  This adds an atomic flag to verify_parent_transid,
      and changes it to return EAGAIN if it needs to block to
      properly verifiy things.
