    blkcg: kill blkio_policy_node · 4bfd482e

    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
    cftype_blkg_same_policy() is dropped along with other policy functions
    for consistency.  Its one line is open coded in the only user -
    -v2: Update to reflect the retry-on-bypass logic change of the
         previous patch.
