This flag doesn't conform to any POSIX standard nor is found in any OS out there. The idea behind this mount flag is to ensure that only non-regular files will be placed in a filesystem, which includes device nodes, symbolic links, directories, FIFOs and sockets. Currently, the only valid case for using this mount flag is for TmpFS instances, where we want to mount a TmpFS but disallow any kind of regular file and only allow other types of files on the filesystem.
