During random test as own device to check slub account, we found some slack memory from hashtab_node(kmalloc-64). By using kzalloc(), middle of test result like below: allocated size 240768 request size 45144 slack size 195624 allocation count 3762 So, we want to use kmem_cache_zalloc() and that can reduce memory size 52byte(slack size/alloc count) per each struct.

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.
