If you write "-2 -3 -4" to the "versions" file, it will notice that no versions are enabled, and nfsd_reset_versions() is called. This enables all major versions, not no minor versions. So we lose the invariant that NFSv4 is only advertised when at least one minor is enabled. Fix the code to explicitly enable minor versions for v4, change it to use nfsd_vers() to test and set, and simplify the code. Signed-off-by: NeilBrown <neilb@suse.com> Signed-off-by: J.

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.
