If you change the set of filesystems that are exported, then the contents of various directories in the NFSv4 pseudo-root is likely to change. However the change-id of those directories is currently tied to the underlying directory, so the client may not see the changes in a timely fashion. This patch changes the change-id number to be derived from the "flush_time" of the export cache. Whenever any changes are made to the set of exported filesystems, this flush_time is updated. The result is that clients see changes to the set of exported filesystems much more quickly, often immediately. 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.
