nilfs2: add /sys/fs/nilfs2/<device> group
This patch adds creation of /sys/fs/nilfs2/<device> group.
The <device> group contains attributes that describe file
system partition's details:
(1) revision - show NILFS file system revision.
(2) blocksize - show volume block size in bytes.
(3) device_size - show volume size in bytes.
(4) free_blocks - show count of free blocks on volume.
(5) uuid - show volume's UUID.
(6) volume_name - show volume's name.
