The kvm slabs can consume a significant amount of system memory and indeed in our production environment we have observed that a lot of machines are spending significant amount of memory that can not be left as system memory overhead. Also the allocations from these slabs can be triggered directly by user space applications which has access to kvm and thus a buggy application can leak such memory. So, these caches should be accounted to kmemcg. Signed-off-by: Shakeel Butt <shakeelb@google.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
