[PATCH] f2fs: hide unused procfs helpers
From: YueHaibing
Date: Fri Jul 13 2018 - 00:06:48 EST
When CONFIG_PROC_FS isn't set, gcc warning this:
fs/f2fs/sysfs.c:519:12: warning: âsegment_info_seq_showâ 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: âsegment_bits_seq_showâ 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: âiostat_info_seq_showâ 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.
