The only places that cfs_srand is called, the random bits are mixed with bits from get_random_bytes(). So it is equally effective to add entropy to either pool. So we can replace calls to cfs_srand() with calls that add the entropy with add_device_randomness(). That function adds time-based entropy, so we can discard the ktime_get_ts64 calls. One location in lustre_handles.c only adds timebased entropy. This cannot improve the entropy provided by get_random_bytes(), so just discard that call.

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.
