Performance oriented customized Linux kernel based on the mainline kernel.
e699e2c6a6
Currently the kernel accounts the memory for network traffic through mem_cgroup_[un]charge_skmem() interface. However the memory accounted only includes the truesize of sk_buff which does not include the size of sock objects. In our production environment, with opt-out kmem accounting, the sock kmem caches (TCP[v6], UDP[v6], RAW[v6], UNIX) are among the top most charged kmem caches and consume a significant amount of memory which can not be left as system overhead. So, this patch converts the kmem caches of all sock objects to SLAB_ACCOUNT.

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.
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.
