nilfs2: add /sys/fs/nilfs2/<device>/segctor group
This patch adds creation of /sys/fs/nilfs2/<device>/segctor group. The segctor group contains attributes that describe segctor thread activity details: (1) last_pseg_block - show start block number of the latest segment. (2) last_seg_sequence - show sequence value of the latest segment. (3) last_seg_checkpoint - show checkpoint number of the latest segment. (4) current_seg_sequence - show segment sequence counter. (5) current_last_full_seg - show index number of the latest full segment. (6) next_full_seg - show index number of the full segment index to be used next. (7) next_pseg_offset - show offset of next partial segment in the current full segment. (8) next_checkpoint - show next checkpoint number. (9) last_seg_write_time - show write time of the last segment in human-readable format. (10) last_seg_write_time_secs - show write time of the last segment in seconds. (11) last_nongc_write_time - show write time of the last segment not for cleaner operation in human-readable format. (12) last_nongc_write_time_secs - show write time of the last segment not for cleaner operation in seconds. (13) dirty_data_blocks_count - show number of dirty data blocks.
