    block, bfq: delete "bfq" prefix from cgroup filenames · 794b4492
    Angelo Ruocco authored
    When bfq was merged into mainline, there were two I/O schedulers that
    implemented the proportional-share policy: bfq for blk-mq and cfq for
    legacy blk. bfq's interface files in the blkio/io controller have the
    same names as cfq. But the cgroups interface doesn't allow two
    entities to use the same name for their files, so for bfq we had to
    prepend the "bfq" prefix to each of its files. However no legacy code
    uses these modified file names. This naming also causes confusion, as,
    e.g., in [1].
    
    Now cfq has gone with legacy blk, so there is no need any longer for
    these prefixes in (the never used) bfq names. In view of this fact, this
    commit removes these prefixes, thereby enabling legacy code to truly
    use the proportional share policy in blk-mq.
