Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2036995 MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-9/-/merge_requests/326 Upstream Status: RHEL only The mem_cgroup structure is allocated dynamically, self-contained and is not embedded in other data structures. Third-party kernel modules are not supposed to access mem_cgroup structure directly. To support new features, mem_cgroup structure often changes quite a lot over time. However, a number of other important data structures like the task_struct contain pointers to mem_cgroup. So any change to mem_cgroup can affect the kABI signatures of the other data structures leading to kABI breakage. Instead of carefully messaging the mem_cgroup structure every time when change is needed in order not to break kABI signature, it is more efficient to just decouple changes to mem_cgroup from affecting kABI signatures of other data structures by using the RH_KABI_EXCLUDE() macro to exclude mem_cgroup pointers from being included in the computation of kABI signature. This macro is applied to mem_cgroup pointers in the task_struct, bpf_map, fsnotify_group and sock data structures. Signed-off-by: Waiman Long <longman@redhat.com> |

README
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.
