Konstantin Belousov 00ac6a98d8 Add mount option for tmpfs(5) to not use namecache. ... The option "nonc" disables using of namecache for the created mount, by default namecache is used. The rationale for the option is that namecache duplicates the information which is already kept in memory by tmpfs. Since it believed that namecache scales better than tmpfs, or will scale better, do not enable the option by default. On the other hand, smaller machines may benefit from lesser namecache pressure.
