All occurrences of cfs_rand() % X are replaced with prandom_u32_max(X) cfs_rand() is a simple Linear Congruential PRNG. prandom_u32_max() is at least as random, is seeded with more randomness, and uses cpu-local state to avoid cross-cpu issues. This is the first step is discarding the libcfs prng with the standard linux prng. Signed-off-by: NeilBrown <neilb@suse.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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.
