Linus Torvalds 05950213a9 Merge tag 'cgroup-for-6.17-rc6-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup fixes from Tejun Heo:
 "This contains two cgroup changes. Both are pretty low risk.

  - Fix deadlock in cgroup destruction when repeatedly
    mounting/unmounting perf_event and net_prio controllers.

    The issue occurs because cgroup_destroy_wq has max_active=1, causing
    root destruction to wait for CSS offline operations that are queued
    behind it.

    The fix splits cgroup_destroy_wq into three separate workqueues to
    eliminate the blocking.

  - Set of->priv to NULL upon file release to make potential bugs to
    manifest as NULL pointer dereferences rather than use-after-free
    errors"

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 reStructuredText 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.
