| |
| Fix build warnings in f2fs when CONFIG_PROC_FS is not enabled |
| by marking the unused functions as __maybe_unused. |
| |
| ../fs/f2fs/sysfs.c:519:12: warning: 'segment_info_seq_show' defined but not used [-Wunused-function] |
| ../fs/f2fs/sysfs.c:546:12: warning: 'segment_bits_seq_show' defined but not used [-Wunused-function] |
| ../fs/f2fs/sysfs.c:570:12: warning: 'iostat_info_seq_show' defined but not used [-Wunused-function] |
