During v6.2 cycle, there were a series of changes to task cpu affinity handling which fixed cpuset inadvertently clobbering user-configured affinity masks. Unfortunately, they broke the affinity handling on hybrid heterogeneous CPUs which have cores that can execute both 64 and 32bit along with cores that can only execute 32bit code. This late pull request contains two fix patches for the above issue. While reverting the changes that caused the regression is definitely an option, the origial patches do improve how cpuset behave signficantly in some cases and the fixes seem fairly safe, so I think it'd be better to try to fix them first. -----BEGIN PGP SIGNATURE----- iIQEABYIACwWIQTfIjM1kS57o3GsC/uxYfJx3gVYGQUCY+F1Fg4cdGpAa2VybmVs Lm9yZwAKCRCxYfJx3gVYGXK8AP0SuFGMgUQL1gYVGfFG3gMCcxDKHVhdU+UP/N1l oJXEpgEA8DW1otuQZz0+MHUyYHkEIUQ5eVj1f2BJfHRkc5r5Cgo= =MXxv -----END PGP SIGNATURE----- Merge tag 'cgroup-for-6.2-rc7-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup Pull cgroup fixes from Tejun Heo: "During the v6.2 cycle, there were a series of changes to task cpu affinity handling which fixed cpuset inadvertently clobbering user-configured affinity masks.

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.
