Subject[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

+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.
