From: "J. Bruce Fields" <bfields@xxxxxxxxxx> 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nfsd(7) man page has some useful documentation of the files under /proc/fs/nfsd/ and proc/net/rpc, but it's many years out of date.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.
