This avoids a bogus negative name cache entry from persisting forever when another client creates an entry with the same name within the same NFS server time of day clock tick. Unlike 8.x and later, the timeout is only adjustable via a system-wide sysctl (vfs.nfs.negative_name_timeout) rather than a mount option. Setting the timeout to 0 disables negative name caching. I also fixed one obvious typo where args.timeo should be args.maxgrouplist. END
