f2fs: print type for each segment in segment_info's show
The original segment_info's show looks out-of-format: cat /proc/fs/f2fs/loop0/segment_info 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 512 512 512 512 512 512 512 512 0 0 512 348 0 263 0 0 512 0 0 512 512 512 512 0 512 512 512 512 512 512 512 512 512 511 328 512 512 512 512 512 512 512 512 512 512 512 512 512 0 0 175 Let's fix this and show type for each segment. cat /proc/fs/f2fs/loop0/segment_info format: segment_type|valid_blocks segment_type(0:HD, 1:WD, 2:CD, 3:HN, 4:WN, 5:CN) 0 2|0 1|0 0|0 0|0 0|0 0|0 0|0 0|0 0|0 0|0 10 0|0 0|0 0|0 0|0 0|0 0|0 0|0 0|0 0|0 0|0 20 0|0 0|0 0|0 0|0 0|0 0|0 0|0 0|0 0|0 0|0 30 0|0 0|0 0|0 0|0 0|0 0|0 0|0 0|0 0|0 0|0 40 0|0 0|0 0|0 0|0 0|0 0|0 0|0 0|0 0|0 0|0 50 3|0 3|0 3|0 3|0 3|0 3|0 3|0 0|0 3|0 3|0 60 3|0 3|0 3|0 3|0 3|0 3|0 3|0 3|0 3|0 3|512 70 3|512 3|512 3|512 3|512 3|512 3|512 3|512 3|0 3|0 3|512 80 3|0 3|0 3|0 3|0 3|0 3|512 3|0 3|0 3|512 3|512 90 3|512 0|512 3|274 0|512 0|512 0|512 0|512 0|512 0|512 3|512 100 3|512 0|512 3|511 0|328 3|512 0|512 0|512 3|512 0|512 0|512 110 0|512 0|512 0|512 0|512 0|512 0|512 0|512 5|0 4|0 3|512 Signed-off-by: Chao Yu <chao2.yu@samsung.com> Signed-off-by: Jaegeuk Kim <jaegeuk.kim@samsung.com>
