Bruce Fields) Sender: linux-nfs-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-nfs@vger.kernel.org From: "J. Bruce Fields" The nfsd(7) man page has some useful documentation of the files under /proc/fs/nfsd/ and proc/net/rpc, but it's many years out of date. As a start, banish any discussion of the long-deprecated nfsctl systemcall to a NOTES section at the end, and admit that there are more than 3 files under /proc/fs/nfsd/. Signed-off-by: J.
