When CONFIG_PROC_FS isn't set, gcc warning this:
fs/f2fs/sysfs.c:519:12: warning: ‘segment_info_seq_show’ defined but not used [-Wunused-function]
static int segment_info_seq_show(struct seq_file *seq, void *offset)
^
fs/f2fs/sysfs.c:546:12: warning: ‘segment_bits_seq_show’ defined but not used [-Wunused-function]
static int segment_bits_seq_show(struct seq_file *seq, void *offset)
^
fs/f2fs/sysfs.c:570:12: warning: ‘iostat_info_seq_show’ defined but not used [-Wunused-function]
static int iostat_info_seq_show(struct seq_file *seq, void *offset)
We can fix the warning by adding the same #ifdef around them.

Could you check below patch sent from Randy Dunlap? It has already fixed this
issue, anyway, thanks for your patch. :)
