[ Upstream commit c54f24e338ed2a35218f117a4a1afb5f9e2b4e64 ] We're unintentionally limiting the number of slots per nfsv4.1 session to 10. Often more than 10 simultaneous RPCs are needed for the best performance. This calculation was meant to prevent any one client from using up more than a third of the limit we set for total memory use across all clients and sessions. Instead, it's limiting the client to a third of the maximum for a single session. Fix this.

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.
