nilfs2: add /sys/fs/nilfs2/<device>/superblock group
This patch adds creation of /sys/fs/nilfs2/<device>/superblock group. The superblock group contains attributes that describe superblock's details: (1) sb_write_time - show previous write time of super block in human-readable format. (2) sb_write_time_secs - show previous write time of super block in seconds. (3) sb_write_count - show write count of super block. (4) sb_update_frequency - show/set interval of periodical update of superblock (in seconds). You can set preferable frequency of superblock update by command: echo <value> > /sys/fs/nilfs2/<device>/superblock/sb_update_frequency Signed-off-by: Vyacheslav Dubeyko <Vyacheslav.Dubeyko@hgst.com> Cc: Vyacheslav Dubeyko <slava@dubeyko.com> Cc: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp> Cc: Michael L.
