PATCH 1/3 Documentation: update seq_file
Starting with commit v3.2-rc4-1-g02125a8, seq_path_root() no longer changes the value of root.
Starting with commit v3.2-rc7-104-g8c9379e, some arguments of seq_path() and seq_path_root() are const.

There is also a pair of functions for printing filenames: - int seq_path(struct seq_file *m, struct path *path, char *esc); - int seq_path_root(struct seq_file *m, struct path *path, - struct path *root, char *esc) + int seq_path(struct seq_file *m, const struct path *path, + const char *esc); + int seq_path_root(struct seq_file *m, const struct path *path, + const struct path *root, const char *esc) Here, path indicates the file of interest, and esc is a set of characters which should be escaped in the output. A call to seq_path() will output the path relative to the current process's filesystem root. If a different -root is desired, it can be used with seq_path_root(). Note that, if it -turns out that path cannot be reached from root, the value of root will be -changed in seq_file_root() to a root which *does* work. +root is desired, it can be used with seq_path_root(). If it turns out that +path cannot be reached from root, seq_path_root() returns SEQ_SKIP. Making it all work
