Now that blkcg configuration lives in blkg's, blkio_policy_node is no longer necessary. Kill it. blkio_policy_parse_and_set() now fails if invoked for missing device and functions to print out configurations are updated to print from blkg's. cftype_blkg_same_policy() is dropped along with other policy functions for consistency. Its one line is open coded in the only user - blkio_read_blkg_stats(). -v2: Update to reflect the retry-on-bypass logic change of the previous patch.
