The previous code artificially limited writeback rate to 1000000 blocks/second (NSEC_PER_MSEC), which is a rate that can be met on fast hardware. The rate limiting code works fine (though with decreased precision) up to 3 orders of magnitude faster, so use NSEC_PER_SEC. Additionally, ensure that uint32_t is used as a type for rate throughout the rate management so that type checking/clamp_t can work properly. bch_next_delay should be rewritten for increased precision and better handling of high rates and long sleep periods, but this is adequate for now.

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.
