  blkcg: Update MAINTAINERS entry (2022-10-17 09:27:18 -1000)

----------------------------------------------------------------
cgroup fixes for v6.1-rc1

* Fix a recent regression where a sleeping kernfs function is called with
  css_set_lock (spinlock) held.

* Revert the commit to enable cgroup1 support for cgroup_get_from_fd/file().
  Multiple users assume that the lookup only works for cgroup2 and breaks
  when fed a cgroup1 file. Instead, introduce a separate set of functions to
  lookup both v1 and v2 and use them where the user explicitly wants to
  support both versions.

* Compat update for tools/perf/util/bpf_skel/bperf_cgroup.bpf.c.

* Add Josef Bacik as a blkcg maintainer.
