Kernel for Galaxy S24, rebased on CLO sources (WIP)
fc4db90fe7
Currently mem_cgroup_from_obj() is not working properly with objects allocated using vmalloc(). It creates problems in some cases, when it's called for static objects belonging to modules or generally allocated using vmalloc(). This patch makes mem_cgroup_from_obj() safe to be called on objects allocated using vmalloc(). It also introduces mem_cgroup_from_slab_obj(), which is a faster version to use in places when we know the object is either a slab object or a generic slab page (e.g. when adding an object to a lru list).

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.
