nilfs2: add /sys/fs/nilfs2/<device>/segments group
This patch adds creation of /sys/fs/nilfs2/<device>/segments
group.
The segments group contains attributes that describe
details about volume's segments:
(1) segments_number - show number of segments on volume.
(2) blocks_per_segment - show number of blocks in segment.
(3) clean_segments - show count of clean segments.
(4) dirty_segments - show count of dirty segments.
