The allocated size for each ebitmap_node is 192byte by kzalloc(). Then, ebitmap_node size is fixed, so it's possible to use only 144byte for each object by kmem_cache_zalloc(). It can reduce some dynamic allocation size. Signed-off-by: Junil Lee <junil0814.lee@lge.com> Signed-off-by: Paul Moore <paul@paul-moore.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.
