    block: misc updates to blk_get_queue() · 09ac46c4
    Tejun Heo authored
    * blk_get_queue() is peculiar in that it returns 0 on success and 1 on
      failure instead of 0 / -errno or boolean.  Update it such that it
      returns %true on success and %false on failure.
    
    * Make sure the caller checks for the return value.
    
    * Separate out __blk_get_queue() which doesn't check whether @q is
      dead and put it in blk.h.  This will be used later.
    
    This patch doesn't introduce any functional changes.
