Pull cgroup fixes from Tejun Heo: - 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. * tag 'cgroup-for-6.1-rc1-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: blkcg: Update MAINTAINERS entry mm: cgroup: fix comments for get from fd/file helpers perf stat: Support old kernels for bperf cgroup counting bpf: cgroup_iter: support cgroup1 using cgroup fd cgroup: add cgroup_v1v2_get_from_[fd/file]() Revert "cgroup: enable cgroup_get_from_file() on cgroup1" cgroup: Reorganize css_set_lock and kernfs path processing
