* 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. -----BEGIN PGP SIGNATURE----- iIQEABYIACwWIQTfIjM1kS57o3GsC/uxYfJx3gVYGQUCY03MlA4cdGpAa2VybmVs Lm9yZwAKCRCxYfJx3gVYGTkUAQD7fNcSPuc2m/BvW+gySKQkp9PZMA6E6yOIqirc QKmIgwEAwWECW7RR1alhOGD50RtYkuYVsLD1+6Ka4eMHe+EhwA4= =kGLI -----END PGP SIGNATURE----- Merge tag 'cgroup-for-6.1-rc1-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup 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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
