I believe those paths are important to users.
When CONFIG_SYSFS is disabled, they are printed in /proc/mounts (and has
severer limit).

Addition to set limit, there is one more reason to adopt seq_file.
Because the printed string is a path, it may contain unprintable
characters. seq_file has a good interface seq_path() which supports
escaping such characters.
